VirtualThreadExtension does not take super classes into account

[bdeneuter]

Describe the bug

A lot of our test classes have a single super class which contains the @ShouldNotPin annotation. The class VirtualThreadExtension does not take super classes into account when determing if recording is needed:
https://github.com/quarkusio/quarkus/blob/main/independent-projects/junit5-virtual-threads/src/main/java/io/quarkus/test/junit5/virtual/internal/VirtualThreadExtension.java#L65

Expected behavior

When a super class declares the @ShouldNotPin annotation that the extension validates that no pinning occurs.

Actual behavior

The @ShouldNotPin annotation is ignored

Fancy a PR as you found the place where we need to check for the super class?

[bdeneuter]

Yes, of course. When I find the time I will create the PR
