NFR: update document server status on any successful document server connection

[mjmccarn]

Test2.docx The new "background job for checking editors availability" seems to change the detection of the ONLYOFFICE document server

Configuration:

• nextcloud 27.0.2 (up-to-date)
• BOTH Collabora and ONLYOFFICE enabled
• Regular testing that both Collabora and ONLYOFFICE work
• ONLYOFFICE is accessible by clicking on "..." next to a document and selecting "Open in ONLYOFFICE"

Historically (for the last 2 years or so), after an update to the docker image for ONLYOFFICE I would need to use or in the client browser to force Nextcloud to recognize ONLYOFFICE and re-enable the "Open in ONLYOFFICE" menu option.

After the last update to onlyoffice-nextcloud, the "Open in ONLYOFFICE" option was not available until after I ran occ onlyoffice:documentserver --check manually. I could, however, open and edit documents if I knew the direct onlyoffice URL (eg https://<nextcloudserver>/index.php/apps/onlyoffice/566480?filePath=%2FTemp%2FTest2.doc)

Recommendation: Any successful ONLYOFFICE editing session should reset the same server access flag that is controlled by the new EditorsCheck process.
