Content create links in Drupal Navigation menu always go to top-level node/add

Actually the ->toString() isn't needed and it doesn't need to be set in a variable. It can just follow the same pattern as for media and blocks:

foreach ($content_types as $item) {
  $content_type_items[] = [
    'title' => $item->label(),
    'class' => $item->id(),
    'url' => Url::fromRoute('node.add', ['node_type' => $item->id()]),
  ];
}

@teknocat great discovery, let's merge this! 👏
