Proposed changes (including videos or screenshots)

The most recent Synapse version 1.158 launched today changed the default room version to 11 which we still don’t support, causing CI to fail since federation tests won’t pass because we only support room version 10.

So I'm pinning Synapse version to the previous version. We'll work on room version 11 later.
