Is your feature request related to a problem? Please describe.
When in the text editor and saving, if the versions tab is open it will not automatically reload the list.
One needs to close the sidebar then open it again.

Describe the solution you'd like
Technically, every editor should trigger a global Javascript event (on the event bus?) so that the sidebar tabs knows that a file has been edited. The versions tab can then listen to that event to reload itself.

Describe alternatives you've considered
N/A

Additional context

@juliushaertl are the text apps and office already triggering such events ?

cc @artonge @CarlSchwan as we discussed this as part of versions.

I suspect that implementing this is rather trivial, most time will likely been spent discussing the name of the event and mechanism 😅

Currently not, but should be straight forward. I think we could just emit the same events that the viewer already uses:

[juliusknorr]

Pushed a pull request for text to emit emit('files:file:updated', { fileid: 123456 }) as viewer already does that for image editing: nextcloud/text#3524

Collabora might be a bit trickier since we don't get a simple saved message from them, but we can track the state of the Doc_ModifiedStatus post message there and consider a save if the status changes from true to false. Will check the next days if that works properly and do a similar PR there then.
