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.

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.

Update borg 1.2.5 -> 1.2.6

add matrix_synapse_oidc_enabled and matrix_synapse_oidc_providers vars

add `ensure-users-created` tag alongside with `ensure-matrix-users-created`

Seems like we don't necessarily need to use a public URL for `SYNCV3_SERVER`.

This possibly helps setups that were having trouble when `SYNCV3_SERVER`
was a public URL (e.g. `https://matrix.DOMAIN`), as described in:
