[pve-devel] [PATCH widget-toolkit 1/2] api-viewer: fix #4271: display nested formats instead of [object Object]

[Matthias Heiserer <m.heiserer@proxmox.com>]

I tried to keep the format as close to the HTML docs as possible, but there are a few discrepancies between HTML docs and how this patch displays parameters:
Instead of <enum>,the enum variants are displayed. [1]
Instead of <0|1>, <boolean> is displayed.

[1] The HTML docs explain parameters after the initial format string, which the GUI doesn't (and there's no space for that).
Showing the variants inline is the easiest way to not loose information here.
