Add support for Drupal 11

I updated the tests and removed support for Drupal 8 since PHPUnit 10 requires Drupal 9 at a minimum.

Thanks for this. I'm hesitant to drop support for Drupal 8 only because of tests. If the module still works with D8, I'd like it to still be installable, even though tests can't be run.

Ok, updated!

Automated tests are failing so setting to "Needs work".

At this moment, and since this is only changing the tests directory, removing support for D8 and D9 would not be entirely justified.
There's still about 170K sites out there running D8 and D9, and maybe they can't upgrade to the next major for some reason, but could keep up with this module.

Ok, tests are now green, so I'm setting to "Needs Review."

Test modules should not have a core_version_requirement as long as they are in package: Testing. See https://www.drupal.org/node/3070687#test →

Taking into account the fact that rector didn't find anything else to be fixed (https://dev.acquia.com/drupal11/deprecation_status/projects/encrypt) and that this only changes tests, and they are now passing, I think this can be merged.

Marking RTBC even if I was the last one committing, since my change was really minor.

This is fantastic, thanks!
