Well, those
- don't themselves have Attr nodes or AttrKinds, so the API couldn't query for
them
- don't actually have any documentation as far as I can tell
So I'm not sure there's much to fix.

The ParsedAttr-kind vs Attr-kind distinction, and the fact that many attributes
don't leave any AST nodes at all, mean this method doesn't seem "universal".
But the goal is to show docs in clangd when hovering on an attribute (which we
only support for those with AST nodes).
If we want to do something different (like show documenation while
code-completing) we'll probably have to add a second ParsedAttrKind-based API.

Thanks, changed it to an if() instead.
(I don't think it's particularly pressing to allow them to be documented)
