Class templates should be able to declare `@ResourceLock`

[marcphilipp]

Steps to reproduce

1. Annotate a @ClassTemplate class with @ResourceLock("key")
2. See it fail with "Dynamic test descriptors must not declare exclusive resources"

Context

• Used versions (Jupiter/Vintage/Platform): 5.14.1 / 6.0.1
• Build Tool/IDE: irrelevant

Deliverables

• Allow @ResourceLock on @ClassTemplate classes

Hello 👋
I'm interested in this issue.
I’d like to ask if there are any considerations or potential solutions you have in mind for this issue. 💡

Sure, go ahead! The problem is that ClassTemplateInvocationTestDescriptor.getExclusiveResources() returns a non-empty set. It might suffice to override that to return an empty set (and check/ensure that we have sufficient test coverage) since ClassTemplateTestDescriptor.getExclusiveResources() should already include class-level resources.
