The following alias templates needs to be defined differently since C++23.
https://github.com/llvm/llvm-project/blob/b46f16c8d7f4a9e37271cdc4717dd858a4c813dc/libcxx/include/__iterator/iterator_traits.h#L469-L479

After changing this alias templates, it should be tested that class template argument deduction (for `map`, `multimap`, `unordered_map`, `unordered_multimap`, `flat_map`, and `flat_multimap`) actually works with tuple-like types.
