Allow connections to newer MariaDB databases

[Joo200]

With MariaDB it's not possible anymore to connect to the database with the mysql database connector.

I already have the mariadb connector added to my server so I don't need it in LWC. It can be added and shaded if needed.

This PR allows to specify the new connection type "mariadb", since mariadb and mysql has the same capabilities there is no other change needed.

Thank you for the PR, but I'm not really a huge fan of this for a few reasons. One is that this does not include the MariaDB connector anyway, so generally useless outside of cases where you include it yourself as mentioned. At the same time I am not fond of shading in this connector specifically for the few users that use it. Bukkit only includes the connector for SQLite and MySQL, and LWC has never explicitly supported MariaDB to begin with. I don't believe that hacking this on makes much sense, as this shift implies that MariaDB plans to make further breaking changes, in which case, an entirely separate implementation catered to MariaDB makes far more sense rather than piggybacking off of the mess that is PhysDB.

That said, I don't really see it happening right now, however that could change in the future (for example, if Bukkit decides to change the connectors they include, etc).

Will have to see. 👀
