docstring: Return database migrations to be executed in this update.
  
  Database migrations should be defined here, instead of in `doUpdate()`, since this method is used
  in the `core:update` command when displaying the queries an update will run. If you execute
  migrations directly in `doUpdate()`, they won't be displayed to the user. Migrations will be executed in the
  order as positioned in the returned array.
