[PATCH proxmox] pbs-api-types: reword outdated maintenance type docstrings

[Christian Ebner <c.ebner@proxmox.com>]

There are now more maintenance types than 'read-only' and 'offline'.

Since listing them all is not really feasible anymore, do not
explicitley mention the type variants in the docstring.
