Enable Podman auto-updates for Redis and MariaDB

Container auto-updates are scheduled for 30 minutes past every hour, or
approximately 30 minutes after `coreos-home-server-update` runs, in
order to give enough time for container builds to complete; only
containers with auto-updates enabled are eligible, however.

This also enables health-checks for Redis, and updates the version to
7.2.
