Wrong class used in turbo streams

TurboBundle::STREAM_FORMAT doesn't exist, that static variable was moved to TurboStreamResponse::STREAM_FORMAT.
Also the stream didn't work for me unless I changed:
$this->render('task/success.stream.html.twig', ['task' => $task]); to $this->render('task/success.stream.html.twig', ['task' => $task], new TurboStreamResponse());
