text: Title: Set plugin migration version in between each migration
  Body: https://github.com/CTFd/CTFd/blob/e1991e16963b10302baa7cc50d52071a5053bf2f/CTFd/plugins/migrations.py#L72-L77
  
  This code here probably should be setting the plugin version in between each migration so that if a migration fails it doesn't need to be started from the beginning again.
