Thanks! 😻 This should make it easier than ever for contributors to find and fix their validation problems.

I pushed a bunch of nitpicks and one enhancement: using the new strategy for disallowed characters. This helps ADO present all errors on the first page, instead of hiding the rest behind more details.

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.

Thanks for making it easier than ever to conform to the repo's formatting requirements! 😻 📈 🎉
