CommentController::getReplyForm() docblock has a copy paste error

The docblock from CommentController::getReplyForm() contains "an associative array containing" twice. I think it the second list should be removed.

   *   An associative array containing:
   *   - An array for rendering the entity or parent comment.
   *     - comment_entity: If the comment is a reply to the entity.
   *     - comment_parent: If the comment is a reply to another comment.
   *   - comment_form: The comment form as a renderable array.
   *   - An associative array containing:
