After some checking, it seems like there's `/_synapse/client/oidc`,
but no such thing as `/_synapse/oidc`.

I'm not sure why we've been reverse-proxying these paths for so long
(even in as far back as the `matrix-nginx-proxy` days), but it's time we
put a stop to it.

The OIDC docs have been simplified. There's no need to ask people to
expose the useless `/_synapse/oidc` endpoint. OIDC requires
`/_synapse/client/oidc` and `/_synapse/client` is exposed by default
already.

10 seconds is a better default for slower (or overloaded) servers

Traefik also serves an internal entrypoint that all addon services
(bridges, bots, etc.) depend on, so it makes sense to have it be
available early on. It is injected as a systemd `required` dependency
for all services, so it would have been pulled earlier anyway (despite
the priority). Nevertheless, it's better to make the playbook-defined
priotities for services match, so that services are explicitly asked to
start in a more correct order.

With these changes in place now, all "start service" tasks executed by
Ansible cause a "change", indicating that all these services are started
in the correct order and none of them is unintentionally started as a
dependency for another.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3102

We likely weren't handling the `matrix_playbook_reverse_proxy_type: other-traefik-container`
case well before. Now, we should be.

Issues and Pull Requests were not migrated to the new
organization/repository, so `matrix-org/synapse/pull` and
`matrix-org/synapse/issues` references were kept as-is.

`matrix-org/synapse-s3-storage-provider` references were also kept,
as that module still continues living under the `matrix-org` organization.

This patch mainly aims to change documentation-related things, not actual
usage in full yet. For polish that, another more comprehensive patch is coming later.

Supersedes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3110

Update broken links in reverse proxies docs

Update dock.mau.dev/mautrix/discord Docker tag to v0.6.5

Update dock.mau.dev/mautrix/gmessages Docker tag to v0.2.4

Updated Grafana dashboard for MMR

Update vectorim/element-web Docker tag to v1.11.54

Update dependency prometheus to v2.49.1-0

Seems like calling these tasks got removed at some point
while merge the `bye-bye-nginx-proxy` branch.

Update Draupnir to 1.86.0 and include changelog entry about new License

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3095

This also supposedly improves the default container network for
`matrix-static-files` for the `other-traefik-container` reverse-proxy
type.

Update dependency prometheus to v2.49.0-0

Not that it seems necessary right now, but it makes it consistent with
all other roles.
