We were notified by EMS that we should update the contents of our
Matrix homeserver client domain data for better OIDC support in
legacy mobile clients, in the wake of the recent authentication
change. This likely doesn't impact us since we don't host accounts
for non-bot users, but gets our configuration consistent with their
expectations so they won't pester us about it in the future.
