Add method to retrieve the transition in "StateTransitionConfirmForm"

The field name and transition id are passed to the form builder, so you can recover the transition. I have always used below approach:

  $build_info = $form_state->getBuildInfo();
  [$field_name, $transition_id] = $build_info['args'];

  $state_item = $build_info['callback_object']->getEntity()->get($field_name)->first();
  /** @var \Drupal\state_machine\Plugin\Workflow\WorkflowTransition $transition */
  $transition = $state_item->getWorkflow()->getTransition($transition_id);

But I must say that your method looks much better. It can then be accessed via $form_state->getFormObject()->getTransition()?

Confirming this works and it is a much better method than what I used.

Committed!
