fix: macOS 13 clang cannot hash std::filesystem::path

Browse Source 
Work around another issue on macOS 13 where trying to build an
`std::unordered_set<std::filesystem::path>` results in an error
because `std::hash<std::filesystem::path>` is not provided.

Simply use the unix path instead, this should make no difference
and might even be slightly faster.
