Issue #3484799 by vladimiraus: EntityAccessCheck documentation contains errors

   *

   * For example, this route configuration invokes a permissions check for

   * 'update' access to entities of type 'node':

   *

   * @code

   * pattern: '/foo/{node}/bar'

   * example.route:

   *   path: '/foo/{node}/bar'

   *   requirements:

   *     _entity_access: 'node.update'

   * @endcode

   *

   * And this will check 'delete' access to a dynamic entity type:

   *

   * @code

   * example.route:

   *   path: foo/{entity_type}/{example}

   *   path: '/foo/{entity_type}/{example}'

   *   requirements:

   *     _entity_access: example.delete

   *     _entity_access: 'example.delete'

   *   options:

   *     parameters:

   *       example:

   * @param \Symfony\Component\Routing\Route $route
