sonarr: Deploy Sonarr in a Podman container

The `sonarr.yml` playbook and corresponding role deploy Sonarr, the
indexer manager for the *arr suite, in a Podman container.

Note that we're relocating the log files from the Sonarr AppData
directory to `/var/log/sonarr` so they can be picked up by Fluent Bit.
