MariaDB Support

[nexrail]

Hello

Currently use TrinityCore and want to move to AzerothCore, but seems you have removed the MariaDB Support.
Is there a reason for that?
As a modern, modular, and performance-focused project, i think mariadb need also have support,

MariaDB support was dropped awhile ago #19451
