  e65d19884 Run Element Web in tightened/read-only mode without a custom nginx config

and issue
  https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/4199

Related to:

- https://github.com/element-hq/element-web/pull/29471
- 16f9e7dd46

Newer Element Web versions allow for the nginx port to be
overriden, etc., and provide instructions for running in read-only mode.

This makes our custom `nginx.conf` patches unnecessary.

Passing the correct `ELEMENT_WEB_PORT` environment variable
also helps with future changes.

Another benefit of this (besides keeping closer to upstream
recommendations and the improved simplicity) is that:

- the container can run its entrypoint env-substitutions code now,
  without reporting errors

- IPv6 for nginx works, so `matrix-client-element:8080` is accessible
  via IPv6 on the container network now
  (this affects only for Traefik's communicaton with Element Web
  internally; public connectivity was handled by Traefik and IPv6 was
  available there even before)

`-t` works on both old and new Docker versions, so it's best to use that.

* Replace "Element" with "Element Web"

- If Element indicates the web application, then it is changed to Element Web.
- If it indicates clients branded with Element such as Element desktop, web, mobile clients, then it is changed to Element clients.
- If it is combined with location sharing functionality, it is not changed.

with other some changes, including:

- Change "app.element.io" anchor link to "https://github.com/element-hq/element-web" on README.md, following other documentation files

Previously, it had to go through matrix-nginx-proxy.
It's exposed to Traefik directly via container labels now

This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.
