fix: return mapped port from MariaDBContainer.getLivenessCheckPortNumbers

MariaDBContainer.getLivenessCheckPortNumbers() returned the hardcoded
internal port (3306) instead of the mapped external port. This was
originally fixed for other containers in PR #5734 but MariaDB was
missed. The new MariaDBContainer class (PR #11083) then copied the
same buggy implementation.

Delegate to super.getLivenessCheckPortNumbers() which correctly maps
internal ports to external mapped ports via getMappedPort().

Applied to both:
- org.testcontainers.mariadb.MariaDBContainer (current)
- org.testcontainers.containers.MariaDBContainer (deprecated)

Fixes #10359
