A recent commit [1] changed the `Display` implementation of `TimeSpan` such
that minutes are now displayed as `20m` instead of `20min`.
This commit adapts the tests for the notification template renderer
accordingly.
[1] 19129960 ("time: display minute/month such that it can be parsed again")

This target type allows users to perform HTTP requests to arbitrary
third party (notification) services, for instance
ntfy.sh/Discord/Slack.
The configuration for these endpoints allows one to freely configure
the URL, HTTP Method, headers and body. The URL, header values and
body support handlebars templating to inject notification text,
metadata and secrets. Secrets are stored in the protected
configuration file (e.g. /etc/pve/priv/notification.cfg) as key value
pairs, allowing users to protect sensitive tokens/passwords.
Secrets are accessible in handlebar templating via the secrets.*
namespace, e.g. if there is a secret named 'token', a body
could contain '{{ secrets.token }}' to inject the token into the
payload.
A couple of handlebars helpers are also provided:
- url-encoding (useful for templating in URLs)
- escape (escape any control characters in strings)
- json (print a property as json)
In the configuration, the body, header values and secret values
are stored in base64 encoding so that we can store any string we want.

To: pve-devel, pbs-devel
All in all pretty similar to other endpoint APIs.
One thing worth noting is how secrets are handled. We never ever
return the values of previously stored secrets in get_endpoint(s)
calls, but only a list of the names of all secrets. This is needed
to build the UI, where we display all secrets that were set before in
a table.
For update calls, one is supposed to send all secrets that should be
kept and updated. If the value should be updated, the name and value
is expected, and if the current value should preseved, only the name
is sent. If a secret's name is not present in the updater, it will be
dropped. If 'secret' is present in the 'delete' array, all secrets
will be dropped, apart from those which are also set/preserved in the
same update call.

Add helper functions to convert from a utf8 string to a base64 string
and vice-versa. Using the TextEncoder/TextDecoder we can support unicode
such as emojis as well [0].

The widgets for editing the headers/secrets were adapted from
the 'Tag Edit' dialog from PVE's datacenter options.
Apart from that, the new dialog is rather standard. I've decided
to put the http method and url in a single row, mostly to
save space and also to make it analogous to how an actual http request
is structured (VERB URL, followed by headers, followed by the body).
The secrets are a mechanism to store tokens/passwords in the
protected notification config. Secrets are accessible via
templating in the URL, headers and body via {{ secrets.NAME }}.
Secrets can only be set/updated, but not retrieved/displayed.

I re-checked this now with a bit more time and while it works fine I
think there can be still some UX enhancements:
- Move the "Add" buttons below the grids, like we do for most other
such UIs (like e.g. in the "Match Rules" tab of the Matcher Add/Edit
window). You probably need to change the layout a bit to keep the
label on top; might want to ask Dominik for how to best achieve that.
Maybe include what is added in the button text, like "Add Header" or
"Add Secret"
- always show an emptyText for the key/value fields to better convey
what is what, alternatively show colum headers, but that takes more
space.
- improve validity checking for header/secret fields, without clicking
in them no invalid/required border is shown, but the overall form
state is invalid, thus disabling the window's Add button. This can
be confusing if no field is marked as invalid.

Thanks for the feedback, much appreciated.
Seems like these issues were already taken care of while I was on sick
leave, thanks Dominik!

+Webhook
+~~~~~~~
+
+Webhook notification targets perform HTTP requests to a configurable URL.
+
+The following configuration options are available:
+
+* `url`: The URL to which to perform the HTTP requests.
+Supports templating to inject message contents, metadata and secrets.
+* `method`: HTTP Method to use (POST/PUT/GET)
+* `header`: Array of HTTP headers that should be set for the request.
+Supports templating to inject message contents, metadata and secrets.
+* `body`: HTTP body that should be sent.
+Supports templating to inject message contents, metadata and secrets.
+* `secret`: Array of secret key-value pairs. These will be stored in
+a protected configuration file only readable by root. Secrets can be
+accessed in body/header/URL templates via the `secrets` namespace.
+* `comment`: Comment for this target.
+
+For configuration options that support templating, the
+https://handlebarsjs.com/[Handlebars] syntax can be used to
+access the following properties:
+
+* `{{ title }}`: The rendered notification title
+* `{{ message }}`: The rendered notification body
+* `{{ severity }}`: The severity of the notification (`info`, `notice`,
+`warning`, `error`, `unknown`)
+* `{{ timestamp }}`: The notification's timestamp as a UNIX epoch (in seconds).
+* `{{ fields.<name> }}`: Sub-namespace for any metadata fields of the notification.
+For instance, `fields.type` contains the notification type - for all available fields refer
+to xref:notification_events[Notification Events].
+* `{{ secrets.<name> }}`: Sub-namespace for secrets. For instance, a secret named `token`
+is accessible via `secrets.token`.
+
+For convenience, the following helpers are available:
+
+* `{{ url-encode <value/property> }}`: URL-encode a property/literal.
+* `{{ escape <value/property> }}`: Escape any control characters that cannot be
+safely represented as a JSON string.
+* `{{ json <value/property> }}`: Render a value as JSON. This can be useful to
+pass a whole sub-namespace (e.g. `fields`) as a part of a JSON payload
+(e.g. `{{ json fields }}`).
+
+==== Examples
+
+===== `ntfy.sh`
+
+* Method: `POST`
+* URL: `https://ntfy.sh/{{ secrets.channel }}`
+* Headers:
+** `Markdown`: `Yes`
+* Body:
+----
+```
+{{ message }}
+```
+----
+* Secrets:
+** `channel`: `<your ntfy.sh channel>`
+
+===== Discord
+
+* Method: `POST`
+* URL: `https://discord.com/api/webhooks/{{ secrets.token }}`
+* Headers:
+** `Content-Type`: `application/json`
+* Body:
+----
+{
+ "content": "``` {{ escape message }}```"
+}
+----
+* Secrets:
+** `token`: `<token>`
+
+===== Slack
+
+* Method: `POST`
+* URL: `https://hooks.slack.com/services/{{ secrets.token }}`
+* Headers:
+** `Content-Type`: `application/json`
+* Body:
+----
+{
+ "text": "``` {{escape message}}```",
+ "type": "mrkdwn"
+}
+----
+* Secrets:
+** `token`: `<token>`

See :ref:`notifications.cfg` for all configuration options.
+.. _notification_targets_webhook:
+Webhook
+^^^^^^^
+Webhook notification targets perform HTTP requests to a configurable URL.
+
+The following configuration options are available:
+
+* ``url``: The URL to which to perform the HTTP requests.
+ Supports templating to inject message contents, metadata and secrets.
+* ``method``: HTTP Method to use (POST/PUT/GET)
+* ``header``: Array of HTTP headers that should be set for the request.
+ Supports templating to inject message contents, metadata and secrets.
+* ``body``: HTTP body that should be sent.
+ Supports templating to inject message contents, metadata and secrets.
+* ``secret``: Array of secret key-value pairs. These will be stored in
+ a protected configuration file only readable by root. Secrets can be
+ accessed in body/header/URL templates via the ``secrets`` namespace.
+* ``comment``: Comment for this target.
+
+For configuration options that support templating, the
+`Handlebars <https://handlebarsjs.com>`_ syntax can be used to
+access the following properties:
+
+* ``{{ title }}``: The rendered notification title
+* ``{{ message }}``: The rendered notification body
+* ``{{ severity }}``: The severity of the notification (``info``, ``notice``,
+ ``warning``, ``error``, ``unknown``)
+* ``{{ timestamp }}``: The notification's timestamp as a UNIX epoch (in seconds).
+* ``{{ fields.<name> }}``: Sub-namespace for any metadata fields of the
+ notification. For instance, ``fields.type`` contains the notification
+ type - for all available fields refer to :ref:`notification_events`.
+* ``{{ secrets.<name> }}``: Sub-namespace for secrets. For instance, a secret
+ named ``token`` is accessible via ``secrets.token``.
+
+For convenience, the following helpers are available:
+
+* ``{{ url-encode <value/property> }}``: URL-encode a property/literal.
+* ``{{ escape <value/property> }}``: Escape any control characters that cannot
+ be safely represented as a JSON string.
+* ``{{ json <value/property> }}``: Render a value as JSON. This can be useful
+ to pass a whole sub-namespace (e.g. ``fields``) as a part of a JSON payload
+ (e.g. ``{{ json fields }}``).
+
+Example - ntfy.sh
+"""""""""""""""""
+
+* Method: ``POST``
+* URL: ``https://ntfy.sh/{{ secrets.channel }}``
+* Headers:
+
+ * ``Markdown``: ``Yes``
+* Body::
+
+ ```
+ {{ message }}
+ ```
+
+* Secrets:
+
+ * ``channel``: ``<your ntfy.sh channel>``
+
+Example - Discord
