Should we incorporate ObservableMacro macro from swift-syntax examples?

[Matejkob]

Hey there!

While diving deep into our unit tests, I observed that we've adeptly incorporated most of the macro examples from the swift-syntax repository. However, one particular macro seems to have slipped through the cracks: the ObservableMacro. I'm genuinely curious about this. Were there specific reasons or considerations behind leaving it out? Let's discuss and potentially evaluate its integration if it aligns with our library's goals.

Hi @Matejkob, I think that is just an oversight on our part, so if you have time to PR adding it in we'd happily accept it!

Sure think! I've added it in the Incorporate ObservableMacro commit.
