Otherwise the public hookshot url will use http and not https

The newly extracted role also has native Traefik support,
so we no longer need to rely on `matrix-nginx-proxy` for
reverse-proxying to Ntfy.

The new role uses port `80` inside the container (not `8080`, like
before), because that's the default assumption of the officially
published container image. Using a custom port (like `8080`), means the
default healthcheck command (which hardcodes port `80`) doesn't work.
Instead of fiddling to override the healthcheck command, we've decided
to stick to the default port instead. This only affects the
inside-the-container port, not any external ports.

The new role also supports adding the network ranges of the container's
multiple additional networks as "exempt hosts". Previously, only one
network's address range was added to "exempt hosts".

This also updates `docs/configuring-playbook-own-webserver.md`,
trying to make it up-to-date with all recent changes.

Check for empty string instead of Null to verify if an openid_server_name is pinned.

This is an advanced feature with dubious usefulness.
Putting it in the default config just confuses people.

We keep the Makefile for now, but don't mention it to new
users anymore.

configured.

* Correct default values for mautrix whatsapp relaybot variables

* Add documentation for using the relaybot with mautrix whatsapp

This extends the collection with support for seamless authentication at the Jitsi server using Matrix OpenID.

1. New role for installing the [Matrix User Verification Service](https://github.com/matrix-org/matrix-user-verification-service)
2. Changes to Jitsi role: Installing Jitsi Prosody Mods and configuring Jitsi Auth
3. Changes to Jitsi and nginx-proxy roles: Serving .well-known/element/jitsi from jitsi.DOMAIN
4. We updated the Jitsi documentation on authentication and added documentation for the user verification service.

This is a rebuild on Alpinelinux 3.17.0 (previously 3.16.2).
The new container image tag was pushed for arm32 and arm64 architectures
as well (2.13.6-r0 was `amd64`-only due to CI trouble in the past).
