Description Of Change

This PR changes the CI so it uses the start scripts for MariaDB and MySQL. The latest version of this is automatically updated by renovate so that limits the manual work we need to do.

I don't think we want to do anything about the usage of MySQL 5.7.8 instead of 5.7.0, but we should look into the test for MariaDB 10.9/10.10. It seems to store the model correctly but it can't query on the $$ it seems. Something related to jsonPathExtractionQuery probably. But that's not for this PR
