The text_with_summary field formatter plugin has been deprecated as of Drupal 11.5 and moved to a new module named 'text_with_summary'.
That module will be removed from core in Drupal 12 and moved to contrib under the same name.
This change is related to Node module no longer ships with field.storage.node.body.yml, introduced in Drupal 11.3, which people (like myself) may have missed.
