 * REMOVE THIS AFTER SUITABLE LEVEL OF DEV?
 *
 * Drops annotation entity tables explicitly. In a healthy install Drupal's
 * entity storage handler handles this automatically, but an explicit drop here
 * guards against the case where the entity class is unloadable at uninstall
 * time (e.g. mid-development with a broken class definition), which would
 * otherwise leave orphaned tables behind.
 *
 * Note: ContentUninstallValidator runs before this hook and will block
 * uninstall if annotation entities exist. Delete annotation content first:
 *
 * @code
 *   $storage = \Drupal::entityTypeManager()->getStorage('annotation');
 *   $storage->delete($storage->loadMultiple());
 * @endcode
