Track config/image/systemd changes via register: directives and compute
a _restart_necessary variable for each service role, allowing the
systemd_service_manager to skip unnecessary restarts during install-* runs.

Covers 22 service roles: alertmanager-receiver, appservice-draupnir-for-all,
bridge-mautrix-wsproxy (+ syncproxy), cactus-comments, cactus-comments-client,
corporal, element-admin, ldap-registration-proxy, livekit-jwt-service, matrixto,
pantalaimon, prometheus-nginxlog-exporter, rageshake, registration, static-files,
sygnal, synapse-admin, synapse-auto-compressor, synapse-reverse-proxy-companion,
synapse-usage-exporter, and user-verification-service.

ansible-core>=2.19.0 only auto-parses YAML files, not JSON.

Previous ansible-core versions auto-parsed JSON as well, but ansible-core>=2.19.0
doesn't, so we added a `from_json` post-filter.
However, older versions auto-parsing JSON and turning it into a dict, on
which we later run `from_json` is no good.

In this patch, we try to equalize behavior and configure Ansible to never parse JSON,
hopefully making old-Ansible behave like new Ansible.

It seems like ansible-core 2.19.0 no longer automatically parses template lookup content
as JSON (into a dict) when dealing with template files (be it `file.json.j2` or `file.j2`).

For files detected to contain YAML (`.ya?ml.j2`, but possibly others),
it automatically parses YAML, because the `convert_data` option
for the template lookup defaults to `true`.

From 3.1.4 and onward, container images will be published to ghcr.io instead of docker.io.

These images are built for arm64 and amd64, but not for arm32 anymore.

This:

- brings consistency - no more mixing `_name_prefix` and `_registry_prefix`
- adds extensibility - a future patch will allow reconfiguring all registry prefixes for all roles in the playbook

We still have `_docker_` vs `_container_` inconsistencies.
These may be worked on later.

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.

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.

matrix-corporal 2.3.0 supports Synapse v1.61.0 (which removed
communities/groups support).

2.2.3 is the first container image tag that is available as a multi-arch image
with support for linux/amd64, linux/arm64/v8 (arm64) and linux/arm/v7 (arm32),
so self-building is no longer necessary on all these platforms.

There was also a 2.1.5 security release made today.
2.2.0 contains the same security fix + more.

Both make handling of Client-Server API v3-prefixed requests better.

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1404

2.1.3 fixes a security vulnerability, which allowed attackers to
circuimvent policy checks by sending HTTP requests with trailing slashes.
