Allow TransactionRequest to be alterable

Symfony Event class deprecated 9.1.0... (broke while testing on a Drupal 10 site).

https://www.drupal.org/node/3159012 →

Before:
use Symfony\Component\EventDispatcher\Event;

After:
use Drupal\Component\EventDispatcher\Event;

Tried to update the local patch based on the merge request / feedback and updated EventDispatcher.

Thanks for your help vmarchuck and for that QA and update for Drupal 10, Nathaniel!

Nudging this to RTBC. We've been using the various versions of it since 2019. Would be great to get a maintainer's feedback.

Made several changes / fixes to the patch and committed it.

@jsacksick do you have an interdiff of your changes?

Also super appreciate you taking a look at this and committing it!

I think this is an interdiff of the changes from 16 up through #20.

Looks like some great improvements to me. Thanks!
