Hopefully, this makes it run faster and prevents potential false-positives.

Although.. a false-positive is unlikely anyway.

Warning Borg users before upgrading to Postgres 16

no postgres 16 support with borg, 15 works.

Update synapse v1.93.0 -> v1.94.0

Self-build now requires the new docker buildx/buildkit, so switch
from the ansible docker module to running a docker build command,
like elsewhere.

This adds a custom regex manager so dependencies in yml files can be found.

Without explicitly passing the `media_url` configuration,
Heisenbridge would try to guess it. It works most of the time,
but some people are experiencing trouble with it.

There's no need for wasteful work and for potential unreliability,
so we now configure the `media_url` explicitly.
