It:

- adds some missing variables
- version variable to branch variable conversion

While it improves the situation, it still doesn't result in a working
self-building feature, because:

- cloning a repository containing submodules requires special care,
  as described here
  (c03ef20e5d/README.md (initial-build-setup))

- we likely better clone a specific repository version from the very beginning, instead of trying to change subsequently (and having to re-initilize submodules)
  though that's very different than what we're doing elsewhere and is likely very wasteful

- we can't just build a `Dockerfile`, we need to invoke `make setup` (`./setup.sh`)

- it's likely that the `docker-src` directory is not reusable across
  versions or may require special handling to clean up files, etc.

* 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

* Replace "SchildiChat" with "SchildiChat Web"

- If it is combined with location sharing functionality, it is not changed.

`matrix_client_schildichat_docker_image` was adjusted to use the
Github Container Registry in 171f5f84a2cd058f0c53780, but the Renovate marker was not adjusted.

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.

Technically, it may still work for Schildichat, because it's stuck in
the past. It will catch up soon anyway.

Putting each client into its own network was good for isolation,
but it's quite wasteful in terms of the container network pool.
