Attempt to remove ImageStyleDownloadController override completely

This version seems to fix issues around overriding the Drupal\image\Controller\ImageStyleDownloadController completely and is much more elegant. We will need to test to make sure everything is flushing correctly when the image is replaced.

This should give us a path forward for modules like ImageAPI Optimize AVIF → to run alongside this module without needing glue modules like ImageAPI Optimize AVIF & WebP → .

I had this consistently working and now with a fresh install it's not... needs more work.

This should be working better now.

For those still on 2.0.0 here is a patch from the MR16.

Needed this path after we've got an error after upgrading the module

PHP Fatal error:  Declaration of Drupal\imageapi_optimize_webp\Controller\ImageStyleDownloadController::deliver(Symfony\Component\HttpFoundation\Request $request, $scheme, Drupal\image\ImageStyleInterface $image_style) must be compatible with Drupal\image\Controller\ImageStyleDownloadController::deliver(Symfony\Component\HttpFoundation\Request $request, $scheme, Drupal\image\ImageStyleInterface $image_style, string $required_derivative_scheme) in ..../web/modules/contrib/imageapi_optimize_webp/src/Controller/ImageStyleDownloadController.php on line 36
