Assets are not served over S3

Rerolled patch #15 to work with 2.16.0

#18 works for me. Thanks

While maybe not exactly the same, I believe that ✨ Support the new assets stream wrapper on Drupal 10.1.0+ Needs review should help with this on 10.1+, at least make it store it locally instead of s3fs which is what I would expect for dynamically generated assets.
