Enable CI coverage for the Hibernate Multi-tenancy integration tests

[Sanne]

Description
We'll need to list the new integration test module <artifactId>quarkus-integration-test-hibernate-tenancy</artifactId> among those running with the MariaDB service enabled.

It also needs to be able to login on MariaDB using the root account, using password secret.

This is a follow-up on #8545

Also we should enable native testing: a quick search of the newly added https://github.com/quarkusio/quarkus/tree/master/integration-tests/hibernate-tenancy ITs did not show like it is enabled for native ITs.

@machi1990 right, I believe I did that as well.

Great.

At least I tested it manually that it works also in native mode with mvn clean install -Dtest-mariadb -Ddocker -Dnative ;-)

But indeed it would be good to have both options automated with the regular build.

FWIW, we don't run native tests by default as otherwise the build takes way too long for the occasional contributor. But sure, we want this to be tested - included in native - on CI regularly.

that's what my PR is addressing.
