Create AddOrUpdateAnnotationAttributeTest.java

[JohannesRabauer]

What's changed?

Tried to write a test for Issue #3978
I could not compile the project unfortunately, because of some problems with gradle. Tried the class in a different project though and it threw the expected error.

What's your motivation?

#3978

Anything in particular you'd like reviewers to focus on?

Fix the bug if possible. :)

Anyone you would like to review specifically?

@timtebeek suggested i create an pr for that error.

Perhaps good to instead add the test to the existing test class we already have in
rewrite-java-test/src/test/java/org/openrewrite/java/AddOrUpdateAnnotationAttributeTest.java.

Thanks for getting this started! Having a test already helps on our way to getting this resolved for you.

Sorry to hear about your Gradle issues though; did you already go through our guide to setting up IntelliJ?

I've since moved the test and briefly explored the options for a fix. We could maybe look at something like newAttributeValue.equals(as.getAssignment().toString()) to make changes for non-literals, but I've not yet had time to fully explore that option. Welcome to tag-team on this if you'd like to help out.
