Removed the GTID field from the GaleraState struct

As we're still not sure what to do on the operator side with the GTID we decided to not export it in the `GaleraState`. It would also force us to import the `GaleraState` struct to the operator repository so we chose to just not export it for the moment instead. https://mariadb-operator.slack.com/archives/C056RAECH0W/p1699990598511999?thread_ts=1699350363.009529&cid=C056RAECH0W
