Seems like `default` is not a supported value and will not
make the bridge autoconfigure itself with the correct prefix anymore.

A value of `default` would be taken literally.

f9705b3323 reworked the configuration and missed wiring
these to the existing variables.

We'be already been going against upstream defaults and have been
enabling backfilling for a few other bridges (Messenger, Instagram, Telegram, Twitter).

Now I'm enabling backfilling by default for the remaining ones, for
consistency.

It seems like the new version does not support a `/metrics` endpoint.
We skip keep the Ansible variables, but they're not doing anything.

While working on upgrading the Meta bridges to bridgev2, I've noticed
that {% raw %} and {% endraw %} on lines like that (immediately
preceding `username_template` may cause YAML indentation issues.

With this patch, when `matrix_heisenbridge_path_prefix` is the default
one we use (`/heisenbrdige`), URLs like this are constructed:

https://matrix.DOMAIN/heisenbridge/_heisenbridge/media/SERVER_NAME/MEDIA_ID/CHECKSUM/FILENAME

If `matrix_heisenbridge_path_prefix` is set to `/`, URLs like this are constructed:

https://matrix.DOMAIN/_heisenbridge/media/SERVER_NAME/MEDIA_ID/CHECKSUM/FILENAME

Our Traefik labels support handling both cases correctly.

`matrix_client_schildichat_docker_image` was adjusted to use the
Github Container Registry in 171f5f84a2cd058f0c53780, but the Renovate marker was not adjusted.
