[clang-tidy] fix PR37913, templated exception factory diagnosed correctly
Summary:
PR37913 documents wrong behaviour for a templated exception factory function.
The check does misidentify dependent types as not derived from std::exception.
The fix to this problem is to ignore dependent types, the analysis works correctly
on the instantiated function.
