Investigate "Unchanged files with check annotations" in infrastructure PRs

> Likely a separate concern, but I see in https://github.com/adoptium/infrastructure/pull/2263/files that GH does some extra analysis at the end on linting, do you also see that @gdams ?

Is that the Beta "Unchanged files with check annotations"? That's been around for a while now I think and I've (so far) been ignoring them, but I guess if we want to start trying to clear them up we should create an issue for it (Cant you think of anyone that might be around and able to work on something like that over the next few weeks @karianna? ) :-)

Start by reviewing the Files view and linting analysis in infrastructure PR 2263, then compare the behavior with GitHub's "Unchanged files with check annotations" feature. Done means confirming whether these annotations are expected GitHub behavior and recording a concrete cleanup path or conclusion for infrastructure PRs.
