Get Tokens function is broken.

I believe the issue is the same as here

https://www.drupal.org/project/search_api/issues/3328702 🐛 Second parameter of request->query->get is not allowed to be an array anymore Closed: duplicate

  public function tokens(Request $request) {
    /** @var MetatagToken $metatag_token */
    $metatag_token = \Drupal::service('metatag.token');
    $token_values = array();
    $tokens       = $request->request->get('tokens');
    $data         = $request->request->get('data');

    if (is_null($data)) {
      $data = array();
    }

->

  public function tokens(Request $request) {
    /** @var MetatagToken $metatag_token */
    $metatag_token = \Drupal::service('metatag.token');
    $token_values = array();
    $tokens       = $request->request->all()['tokens'] ?? [];
    $data         = $request->request->all()['data'];

    if (is_null($data)) {
      $data = array();
    }

No more error locally.

#5 work for me on Drupal 10.2.5

After update to Drupal 10.3.5, the patch seems not work.
