The link in https://github.com/nlohmann/json#stl-like-access is broken.
It points to https://en.cppreference.com/w/cpp/concept/ReversibleContainer.
"Concepts" have been renamed to "named requirements".
This is because P0898R3 Standard Library Concepts has been merged into
C++20: cplusplus/draft#2145.
Cppreference have moved their links accordingly.
