fix: add --mysql-native-password=ON param to fix broken connection

fixes #1089
For tutor instances that were created with tutor 15 and earlier and then upgraded to tutor 18, the launch process would fail as MySQL connection could not be made. This is because mysql-native-password was removed in MySQL 8.4.0. We turn it on temporarily to fix failing connections
