Use notify_push for show add / remove of pages

[wargreen]

Is your feature request related to a problem? Please describe.
When friends add / remove pages, i need to reload to see the change.
This lead multiple-create / remove when working together.

Describe the solution you'd like
Use notify_push (the Client Push app) for live update the list of pages.

Describe alternatives you've considered
Use discussion for know when i need F5

Additional context
notify_push is used for desktop client sync, deck live update etc... It seem to me that can fluidize the collective workflow.

Dear @wargreen, this is already the case. Apparently the notify_push implementation broke with Collectives 2.11.0 due to a bug in @nextcloud/axios 2.5.0, but before that version changes to the page list should have get propagated via notify_push.

See initListenPush in Collective.vue for the frontend part and notifyPush() in PageService for the backend part.

Did you actually test whether this works on your instance? As mentioned, with latest Collectives release (2.11.0) it's broken, but if you still run an older instance, you should see a websocket connection to your notify_push service when loading the Collectives app.

Looking into this again I now understood that synchronization via notify_push only works for sessions of the same user so far. So indeed there's more work needed to sync changes between different users.
