localgov_workflows_modules_installed hook doesn't seem to have a matching update hook for existing installs

[bradley-baylis]

As the title says this hook doesn't have a corresponding update from what I can see for existing installs:

/**
 * Implements hook_modules_installed().
 */
function localgov_workflows_modules_installed($modules, $is_syncing) {

  // Fix the core moderated content view.
  if (in_array('localgov_workflows', $modules, TRUE) && !$is_syncing) {

    // Don't change things if the core editorial workflow is enabled.
    if (!is_null(\Drupal::entityTypeManager()->getStorage('workflow')->load('editorial'))) {
      return;
    }

    $moderated_content_view = \Drupal::entityTypeManager()
      ->getStorage('view')
      ->load('moderated_content');
    if ($moderated_content_view) {

      // Fix filters to match editorial workflow.
      $display = $moderated_content_view->get('display');
      $filters = $display['default']['display_options']['filters'];
      $filters['moderation_state']['value'] = [
        'localgov_editorial-draft' => 'localgov_editorial-draft',
        'localgov_editorial-review' => 'localgov_editorial-review',
        'localgov_editorial-archived' => 'localgov_editorial-archived',
      ];
      $filters['moderation_state_1']['value'] = [
        'localgov_editorial-published' => 'localgov_editorial-published',
      ];
      $display['default']['display_options']['filters'] = $filters;

      // Update no results text.
      $display['default']['display_options']['empty']['area_text_custom']['content'] = 'No unpublished content available. Pages in Draft, Review and Archived states appear here.';

      $moderated_content_view->set('display', $display);
      $moderated_content_view->save();
    }
  }
}

Noticed this when we had published content appearing in the 'Unpublished' report. We've already resolved this for ourselves by running the hook code and exporting the new view config, seems to have stopped the incorrect results coming through.
