Support the new assets stream wrapper on Drupal 10.1.0+

Whao, that's nice, thank you @hanoii!

I'd vote for a 3.x semver branch to include this, what do the maintainers think?

Thanks! I thought about that, but I figured that that the change is very minimal that it would make it a burden to have to maintain two separate branches for some time only for this change unless there's a strong opinion that 2.x would is EOL and all will happen in a new 3.x.

Yes I think we could do it like that, but let's wait for maintainer reply.

I like this new approach. I hope it solves the s3 issue as well.

A couple things to change in the MR:
add docblock & return type to the new getDirectoryUri method
There's no need for the "else" condition. Something like below will be more streamlined.

if($is_true) {
  return 'foo';
}
return 'bar';

Addressed feedback.

Please add the return type declaration.

Added the suggestion in the same PR. It is just a small change and credit is to @hanoii
