* Update matrix-domain.conf.j2

exchanged "^~" with "~" as a pattern matching in the location part.
I am very sure, that it only works using "~". I am not quite sure though, if this is the right way to do it, because "~" is probably more expensive than "^~"

the rewrite has to be behind the definition of the $backend. Otherwise nginx will fail to work. This is probably because "break" goes directly to the proxy_pass which uses $backend.

* Update matrix-domain.conf.j2

also change the order of "set $backend" and "rewrite" here in the 3pid registration section

* Update matrix-domain.conf.j2 - repeat v3_to_r0 rewrite in else-statement

as you said: repeat it for the else-case, where the ma1sd might be running on sans_container.

* Update matrix-domain.conf.j2 - corrected wrong variable

atrix_nginx_proxy_proxy_matrix_3pid_registration_v3_to_r0_redirect_enabled
is the right variable to check (twice) in the corresponding branch.

* matrix-domain.conf.j2 - fix-2954: change all whitespaces to tabs as you do it

Currently v3.0.0 tested with no issues.
So remove matrix_user_verification_service_docker_image from groups_vars.

/.npm must be writable or an error will be reported.

It seems like with the default versioning detection strategy (`docker`),
the version is detected up to the hyphen:

> Renovate tries to follow the most common conventions that are used to tag Docker images.
> In particular, Renovate treats the text after the first hyphen as a type of platform/compatibility indicator.

Perhaps with `semver` would be more appropriate for this image.

More details in: https://docs.renovatebot.com/modules/versioning/

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.
