Allow navigating away from unknown room view

[ashfame]

In this PR:

• We bring some change from our fork by updating dependency to the latest master tag. I supposed we would keep them incrementing as needed and tag it when we are ready to release a new version of Chatrix.
• Fix a path which needed to be changed post merge of sync-worker work in our hydrogen fork.
• Override UnknownRoomViewModel class to define a different closeUrl() for single room mode

@psrpinto Build currently fails because it doesn't have that temporary fix we did in Hydrogen for skipping manifest.json

@ashfame https://github.com/Automattic/chatrix/pull/214 fixes the build issue. Once that one gets merged to main, we can rebase this on main and it should build.

I rebased with main to get the build fixes, didn't make any other changes.
