HTTP/3 is no longer considered experimental in Traefik v3,
so it's a good time to enable it.

`matrix-media-repo` is the only role that seems incompatible with the
changes introduced by Traefik v3, due to its use of `PathPrefix` with
regular expressions in a few places.

Regular expressions should now be used with `PathRegexp`, not
`PathPrefix`. Furthermore, they should follow the Golang regexp syntax,
as described in the migration guide:

Upgrade Jitsi (v9584-0 -> v9584-1)

This reverts commit 752de4406e.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3393

When running the playbook against an existing server, it invokes `register_new_matrix_user`
as part of the `matrix-user-creator` role, which runs before the
`systemd_service_manager`. At that time, `matrix-user-creator` detects
that Synapse is up (from before), but it's the old version. Services have not yet been
restarted, so it's actually the older Synapse version that is up, not
the new one. The old version does not support the `--exists-ok` flag yet.

Basically, this `--exists-ok` patch landed too early and has affected existing playbook
users that have an older version of Synapse in operation.

It will be safer to bring back this patch some time in the future.
However, users upgrading from Synapse <= v1.109.0 even long into the
future will bump into the same issue. As such, it would be better to
either add special handling or to delay bringing back this patch enough
so as to ensure everyone using the playbook is on Synapse >= 1.110.0.

`auto_join_mxid_localpart` defines the local part of the user id which is used to create auto-join rooms. The variable needs to be set to invite new users to any auto-join rooms which are set to invite-only.

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`.
