  e65d19884 Run Element Web in tightened/read-only mode without a custom nginx config

and issue
  https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/4199

This probably got fixed with Matrix Authentication Service 0.15.0 though
I'm not sure exactly which commit did it.

Ref: https://github.com/element-hq/matrix-authentication-service/releases/tag/v0.15.0

This is a backward-incompatible change. By default, Ansible creates
users with (e.g.) `/bin/sh` on Linux, so changing to a no shell
leads to different behavior.

That said, it appears that using a shell-less user works OK with regard
to Ansible execution and starting the systemd services/containers later on.

We create the `matrix` user as a system user (smaller uid), so it makes
sense to do the same for the `matrix` group.

This defaults to `true`, as before.

* migration ownership fix

This should allow roles for other forks (like Tuwunel) to use similar tags.

Intentionally not removing the old configuration setting yet, as some bridges may/do not support
the new setting name. It's likely just bridgev2 mautrix bridges that have been updated and support both right now.

Since mautrix-whatsapp v0.12.0, the bridge deals with more than just phone numbers now,
so it sometimes tries to manage users with Matrix IDs like: `@whatsapp_lid-123456789:example.com`
