Issue #3396445 by tstoeckler: [11.x] Remove deprecated ContextProvidersPass

/**

 * Adds the context provider service IDs to the context manager.

 *

 * @deprecated in drupal:10.2.0 and is removed from drupal:11.0.0. The

 *    context.repository service uses the service_id_collector pattern instead

 *    so this is no longer needed.

 *

 * @see https://www.drupal.org/node/3416153
