Package name schema regex is not validated

I hope we can get the regex fix in and then in 📌 Create testing for package_name validation schema Postponed add the test coverage because it seems we can only test this with core 11.x.

But it is possible to test this locally against 11.x using this commit from the MR https://git.drupalcode.org/project/automatic_updates/-/merge_requests/96... before I remove the test cases

Marking as core-mvp because the core MR won't pass without it.

Glad we caught that. It's definitely an invalid regex, so although I don't know why it passes on Drupal 10.1.x, I'm okay with this as-is.

@phenaproxima thanks
