Build/Test Tools: Update the MariaDB test strategy matrix.

This updates the test strategy matrix in the PHPUnit test GitHub Actions workflow to include the most recent MariaDB release, 11.2.

While 11.0 and 11.1 are still maintained, all three are short-term stable releases, which see support dropped after 1 year.

Until a larger discussion around how the project supports database software releases with shorter support windows takes place (short-term in MariaDB or “innovation” releases in MySQL), testing only against the latest short-term release should be sufficient.

Props johnbillion, l1nuxjedi.
