Fix for issue  #58050

Hi,

a quick PR to mention in the compiler error message that `?` is a macro operator, as according to issue #58050

It passed `python x.py test src/tools/tidy`  locally, as well as the recommendation to run `/x.py test src/test/ui --stage 1 --bless`.

Let me know if anything else is needed.
