Support for S3 File Integration module

Why does the DownloadController::download() deals with the file serving?

Would not be easier just to redirect to the file URL, like this?
For all cases, not just for remote files.

class DownloadController {
  public function download(MediaInterface $media): Response {
    // Get the $file as usually.
    return new \Symfony\Component\HttpFoundation\RedirectResponse($file->createFileUrl());
  }

}

I have not tried this, but this fork could possibly be a solution for ✨ Add support for Stage File Proxy Needs review .

@sweetchuck, that is how the module was designed. I didn't want to re architect the whole thing. That is a whole different discussion that should probably be had because it makes sense.

Here is the patch file generated from the fork.

When files are remote (S3fs, stage file proxy), it makes even less sense to for Drupal to fetch them and send a StreamedResponse. Could we use the code from #5 just for remote files? Then a different issue could discuss using a redirect for local files.
