The value of `off` was taken to be a boolean, but it shouldn't be.

Synapse expects a string (currently one of: `all`, `invite`, `off`).

This also removes the `matrix_synapse_version_arm64` variable we've
been dragging around for a long time.

Since https://github.com/matrix-org/synapse/pull/11810, a multiarch Synapse
container image (for AMD64 and ARM64) is released at the same time.

Fixes a issue with room version 1.

Merging has to wait until ARM images are built ofc.

v1.50.0 was found to be buggy for people using a `webclient` listener.
This is fixed in v1.50.1.

We don't use such a listener, so we weren't affected anyway.

This commit simply add encryption_enabled_by_default_for_room_type
variable.

This upgrade is technically not needed due to 1.49.1 and 1.49.2 being identical with a lone fix to Debian packaging being the only change. 

Still some might want us to be on the absolutely latest version even tho these 2 are practically identical.

ARM64 has yet to be built so this has to wait for that before merge.

This update fixes a sync issue that would cause some users to experience sync issues that could cause initial sync to completely fail.

Getting an upstream fix is preferable. In any case, it's probably nice
to have this defined explicitly in our configuration. This way, people
can more easily discover that they can override the URL preview
language.

We had to remove UID/GID environment variables that we used to pass
to the Synapse container, because it was causing a problem after
https://github.com/matrix-org/synapse/pull/11209

We were using both `--user` and UID/GID environment variables until now.
