Maint/test against nc 33

[christianlupus]

Topic and Scope

This is a quick update of the test infrastructure to run any tests against the current stable 33 branch of NC server.

Concerns/issues

I had to mark the app as compatible with NC33 to make the test run. Thus, this should not be merged until support with NC 33 is actually established.

Formal requirements

There are some formal requirements that should be satisfied. Please mark those by checking the corresponding box.

• I did check that the app can still be opened and does not throw any browser logs
• I created tests for newly added PHP code (check this if no PHP changes were made)
• I updated the OpenAPI specs and added an entry to the API changelog (check if API was not modified)
• I notified the matrix channel if I introduced an API change
