chore: consistently use Ansible FQCN in module calls

In order to adhere to Ansible best practices, always use Fully Qualified
Collection Names (FQCN) [1] when calling modules.

Other than that, this commit doesn't apply any further changes
except where needed as a module name has been updated.
The module `ansible.builtin.systemd` has been renamed to
`ansible.builtin.systemd_service` with `ansible.builtin.systemd` just
being an alias [2] for reasons of backward compatibility.
