* Add public url for gitlab hookshot to autocreate webhook on gitlab instance

* Add `noqa var-naming` comment to variable

By appending `/webhook` to the public URL (becoming `/hookshot/webhooks/webhook`)
and by only stripping the `/hookshot/webhooks` prefix,
we're effectively following what newer Hookshot versions advise
(see https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/1681).

This change appears to be backward-compatible (old webhook URLs like `/hookshot/webhooks/:hookId` still work),
until Hookshot behavior changes.

Regression since 78912688734589d67a9213201dbae45d231fad84,
where I removed the `matrix_hookshot_urlprefix` prefix group
`group_vars/matrix_servers`, thinking the value in `roles/custom/matrix-bridge-hookshot/defaults/main.yml`
was the same.

The value in `defaults/main.yml` incorrectly included `matrix_hookshot_public_endpoint`
in `matrix_hookshot_urlprefix`, which was leading to double-`/hookshot`-prefixing.

We were previously saved by the `matrix_hookshot_urlprefix` override in `group_vars/matrix_servers`.

This fix brings the correct URL prefix value (the one without `matrix_hookshot_public_endpoint`)
to `defaults/main.yml`.

With this change, it should be possible for people to adjust the Docker
dependency from `docker.service` to something else (e.g. `pkg-ContainerManager-dockerd.service`),
or to completely eliminate it by setting `devture_systemd_docker_base_docker_service_name` to an empty string.

This makes it easier for people to use the playbook against a Synology DSM server.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3333

matrix_hookshot_github_oauth_redirect_uri was adding an extra https in
front of matrix_hookshot_urlprefix, which already included that.

The conditional check 'matrix_hookshot_experimental_encryption_enabled and matrix_hookshot_cache_redisUri == ''' failed. The error was: An unhandled exception occurred while templating '{{ ('redis://' + matrix_hookshot_cache_redis_host + ':' + matrix_hookshot_cache_redis_port) if matrix_hookshot_cache_redis_host else '' }}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: Unexpected templating type error occurred on ({{ ('redis://' + matrix_hookshot_cache_redis_host + ':' + matrix_hookshot_cache_redis_port) if matrix_hookshot_cache_redis_host else '' }}): can only concatenate str (not \"int\") to str. can only concatenate str (not \"int\") to str

The default Redis port is 6379, not 6739.

Hookshot wants a trailing slash for this route.

If we let Hookshot redirect, it goes to `/widgetapi/v1/static/`,
instead of `/hookshot/widgetapi/v1/static/`, so we take this matter into our
own hands.

Public URLs are like: `/hookshot/widgetapi/v1/static/`
.. which get translated to requests for: `/widgetapi/v1/static/`

Previously, we were stripping the whole `/hookshot/widgetapi` prefix,
which is wrong.

This is still very far from usable.

Various bridges and bots are still talking to
`matrix-nginx-proxy` instead of the new `matrix-homeserver-proxy` role.
These services need to be reworked. While reworking them,
various cleanups are being done as well as adding Traefik-labels to
those that need them.

    draft encryption support for hookshot

Related to: https://matrix.org/blog/2023/07/bridges-security-updates/

This reverts commit f98f803b44.

As the docker image has been released for this version we can now upgrade to this version

This reverts commit 428f7a1f75.

Looks like it won't become a tagged image until a "release" is posted.

Warning! Potentially breaking change: https://github.com/matrix-org/matrix-hookshot/releases/tag/3.0.0
