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.

I haven't really traced it (yet), but on some servers, I'm observing
`ansible-playbook ... --tags=start` completing very slowly, waiting
to stop services. I can't reproduce this on all Matrix servers I manage.
I suspect that either the systemd version is to blame or that some
specific service is not responding well to some `docker kill/rm` command.

`ExecStop` seems to work great in all cases and it's what we've been
using for a very long time, so I'm reverting to that.

ExecStopPost should allow us to clean up (docker kill + docker rm)
even if the ExecStart (docker run ..) command failed, and not just after
a graceful service stop was initiated.

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.

This reverts commit 1fb54a37cb.

Seems like it's been pulled or something. It used to exist, but not
anymore. Not sure what's going on.
