After nextcloud/server#37726 we need to adjust the event that a file has been updated, however we should actually make sure to send a full Node object there not just the fileid.

Note: For the other apps that already started using the old files:file:updated syntax, we should migrate.
As those apps are shipped and have stablexx branches, I think it's safe to change it for master in both server and those apps. Only Notes would be an issue:

nextcloud/notes@f635c5c/src/components/NoteRich.vue#L63 @juliushaertl
nextcloud/text@01ccc7c/src/components/Editor.vue#L637 @juliushaertl
