Last version for Drupal 8 is not Drupal 8 compatible

This is a highly specific issue that applies to an extremely limited use case where there is a very out-of-date site that needs upgrading to D9/D10 but this can only be done by stages ensuring all modules are upgradable before doing it. (Probably just me.)

The 2.0.0-beta1 version is the last one that claims to be Drupal 8 compatible but it isn't because cloudinary_sdk EventSubscriber uses the Kernel::RequestEvent which is not available on D8 and it should be using Kernel::GetResponseEvent.

This fork is solely to modify that event, for the specific use case and need never be incorporated into existing code.
