Shared Secret Auth double puppeting still works for this bridge, but
is deprecated and will go away in the future.

Since upgrading mautrix-slack (and pinning to v0.1.0) in e4b54c37fe258b17f49dd7ed58a18ef3abac1c41,
we expect double-puppeting to require the new appservice double-puppeting method.

This commit switches the mautrix-slack bridge to it.

Since upgrading mautrix-signal (v0.6.3 -> v0.7.0) in 76fec0b8632804194ae54dce3328fef2b6e6b3c2,
we expect double-puppeting to require the new appservice double-puppeting method.

This commit switches the mautrix-signal bridge to it.

Bridges will be switched to this new method in future patches.

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

No need to duplicate the same logic as in `group_vars/matrix_servers`.

Having it disabled by default in the role itself and overriding it at the playbook level (based on the selected homeserver implementation) makes more sense.

Related to:

- https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3470
- https://github.com/hifi/heisenbridge/releases/tag/v1.15.0

During testing, it appears that Heisenbridge generated media URLs
that look like this: `{media_url}/_matrix/media/v3/download/DOMAIN/FILE_ID/FILE_NAME`.

This seems off. We were expecting `{media_url}/_heisenbridge/media/something`
(e.g. `https://matrix.DOMAIN/heisenbridge/_heisenbridge/media/something`, leading to its own media proxy),
but Heisenbridge still seems to be generating URLs destined for the homeserver's Media API.

Until we figure out why that is, `media_url` remains pointed to the homeserver URL (just like before),
so that the bot can continue operating like before.

Cinny includes nginx configuration which does URL rewrites now, as seen
here: https://raw.githubusercontent.com/cinnyapp/cinny/dev/docker-nginx.conf

That said, we have our own nginx configuration for Cinny, because we'd
like to run ngin as non-root and on a non-privileged port (80 -> 8080).

For this reason, we override `/etc/nginx/nginx.conf` and need to
duplicate what we see in `/etc/nginx/conf.d/default.conf` with our own
`server` block (which listens on port 8080).
