    libstdc++: add missing typename for dependent type in ranges::elements_view
[PR100900]

    Clang complains about the missing typename. I believe it's not required
    in a more complete implementation of C++, but it's nicer to support
    less complete implementations.

            PR libstdc++/100900

    libstdc++-v3/ChangeLog:

            * include/std/ranges (elements_view::__iter_cat::_S_iter_cat):
            Add missing typename.
