Fixes #107983, addressing the bad suggestion.
The test can probably be made more specific to this case, but I'm unsure how.

IMO it's overkill to have a blanket ban on suggesting unstable methods. Is there better way to tell whether it's a "you are never meant to use this" method?

Checking for #[doc(hidden)] probably makes sense, and works for this issue
