Collabora updates are undetected

Describe the bug

When updating the collabora server (maybe automatically by unattended-upgrades) the app doesn't notice a version change. I got a lot of logs with version-mismatch errors. This was solved simply by pressing "save" again at the configuration page for the server, which then updated the version nexctloud thought it has.

To Reproduce
Steps to reproduce the behavior:

1. have a collabora server
2. have a nextcloud
3. update collabora server
4. See version update not beeing detected

Expected behavior
Since you show the version and a successful connection in the app, I expected version updates to be automatically detected.
This is either a bug-report or a feature-request.

Server details

Operating system:
Ubuntu24.04

Web server:
yes

Database:
yes

PHP version:
8.2

Nextcloud version:
29.0.3

Version of the richdocuments app
8.4.8

Version of Collabora Online
before: 24.04.8.(something), now 24.04.9.3-1

Configuration of the richdocuments app
No need

Start by reproducing the issue with a Collabora server update and inspect how the richdocuments app handles the server version during configuration saving and successful connections. Compare the stored version before and after the update; done means the app detects the new version automatically without requiring configuration to be saved again.
