Add bulk enable "Generate automatic URL alias"/force option in bulk generate

@lubwn you could use an update hook instead that let's you do bulk updates without timing out if you have many entities and you can also leave the code because it will only execute once on each environment.

function mymodule_update_9001(&$sandbox) {
  // Initialize variables on the first run.
  if (!isset($sandbox['total'])) {
    $entity_list = \Drupal::entityQuery('node')
      ->condition('type', 'my_entity')
      ->execute();
    $langcodes = \Drupal::languageManager()->getLanguages();
    $sandbox['langcodes'] = array_keys($langcodes);
    $sandbox['total'] = count($entity_list);
    $sandbox['current'] = 0;
  }

  // Batch cycle.
  $batch_nids = \Drupal::entityQuery('node')
    ->condition('type', 'my_entity')
    ->range($sandbox['current'], 15)
    ->execute();

  foreach ($batch_nids as $nid) {
    $my_entity = \Drupal::entityTypeManager()->getStorage('node')->load($nid);
    // Loop through all languages.
    foreach ($sandbox['langcodes'] as $langcode) {
      if ($my_entity->hasTranslation($langcode)) {
        $my_entity_translation = $my_entity->getTranslation($langcode);
        // Avoid re-saving nodes that don't need to be updated.
        if ($my_entity_translation->path->pathauto !== 1) {
          $my_entity_translation->path->pathauto = 1;
          $my_entity_translation->save();
        }
      }
    }
    $sandbox['current']++;
  }


  if ($sandbox['current'] >= $sandbox['total']) {
    $sandbox['#finished'] = 1;
    \Drupal::messenger()->addMessage('A total of ' . $sandbox['total'] . ' entities were updated.');

  }
  else {
    $sandbox['#finished'] = ($sandbox['current'] / $sandbox['total']);
    // Output a message to inform about the ongoing process.
    \Drupal::messenger()->addMessage($sandbox['current'] . ' entities were updated out of ' . $sandbox['total']);
  }
}
