This is done for a few reasons:
- less globals and more indepdendence for each role is better. We rely
on various externally-hosted roles and they don't rely on this global
either.
- `matrix_container_global_registry_prefix` could make people think they
could just override this variable and have all their images pull from
elsewhere. This is rarely the case, unless you've taken special care
to mirror all the various components (from their respective
registries) to your own. In such a case, you probably know what you're
mirroring and can adjust individual variables.
- nowadays, various components live on different registries.
With Docker Inc tightening rate limits for Docker Hub, it's even more
likely that we'll see increased diversity in where images are hosted

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.
Please note that This Mjolnir version bump technnically is missing some extra stuff that mjolnir claims we should do but it didnt work when i tried it and well my mjolnir deployment has been running this since release day almost and its fine. No errors in log that are unexpected. (Mjolnir throws errors in the log for anyone who wonders for various things that are fine. Like if a protection is off that is an error. Its due to how matrix-bot-lib works.)
