"bugprone" checks in general are expected to give only warnings for real problems: `setjmp` can be perfectly fine but it's not how exceptions should be modelled in C++, hence "modernize" category.

Thanks for reviewing, I've moved the check to `modernize-avoid-setjmp-longjmp` and kept the CERT link duplicated in both places, as requested.
