With these changes, we:

- install https://github.com/Tecnativa/docker-socket-proxy via the
  https://github.com/devture/com.devture.ansible.role.container_socket_proxy Ansible role

- make Traefik access the Docker API via TCP by connecting to this
  socket proxy

- .. which allows us to run the Traefik container with less privileges
  (non-`root`, dropped capabilities)

This is a mistake made in 10b5350370.

Config was accidently changed when importing upstream changes.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2532

Added doc for self-signed certificates

If someone disables ACME, then they're using their own certificates
somehow. There's nothing to dump from an `acme.json` file.

We don't need these 2 roughly-the-same settings related to the
traefik-certs-dumper role.

For Traefik, it makes sense, because it's a component used by the
various related playbooks and they could step onto each other's toes
if the role is enabled, but Traefik is disabled (in that case, uninstall
tasks will run).

As for Traefik certs dumper, the other related playbooks don't have it,
so there's no conflict. Even if they used it, each one would use its own
instance (different `devture_traefik_certs_dumper_identifier`), so there
wouldn't be a conflict and uninstall tasks can run without any danger.

remove devture services in remove-all script

Update element 1.11.23 -> 1.11.24

Update grafana 9.3.6 -> 9.4.1

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2524

We don't need this anymore. No one should be using matrix-nginx-proxy
anymore.

Add example config + readme for fronting playbook's traefik with own nginx on same server
