Upgrade Ruma to present. The following are intentionally benign for activation in a later commit: - Hydra backports not default. - Room version 12 not default. - Room version 12 not listed as stable. Do not enable them manually or you can brick your database. Signed-off-by: Jason Volk <jason@zemos.net>
