Allow joining calls and video rooms without enabling the labs flags (#95)

robintown · web-flow · commit 86db68d22f3e · 2024-09-30T13:37:00.000Z
Since Element Call has now reached production on Element X, Element Web needs to be able to at least participate in group calls. Starting a group call or creating a video room will still require the labs flags, for now.

Note that Jitsi-based video rooms are also affected by this change. This is not because we intend to delabs them (rather, we intend to get rid of them in favor of Element Call video rooms), but because it's easiest to handle both video room variants consistently.
