JDBC string constructor does not respect port

See

GeyserConnect/src/main/java/org/geysermc/connect/storage/MySQLStorageManager.java

Line 51 in af401dd

    
           connection = DriverManager.getConnection("jdbc:mysql://" + connectionInfomation.getHost() + "/" + connectionInfomation.getDatabase(), connectionInfomation.getUser(), connectionInfomation.getPass());

This means that the custom-servers.mysql.port YAML key is effectively ignored.

I'll be creating a PR shortly if this is not fixed.
