Remove HEDLEY annotation from exception::what()

The latest MSVC compiler throws the following warning on nlohmann::detail::exception::what() if /analyze is enabled: ``` vcruntime_exception.h(93) : warning C28204: 'what' has an override at `nlohmann\json\develop\single_include\nlohmann\json.hpp(2644)` and only the override is annotated for return: when an override is annotated, the base (this function) should be similarly annotated. ``` See https://godbolt.org/z/r331h4
