Replace the full nlohmann_json repo with a fetch_content variant. (#279)

Browse Source 
During the configuring of json-schema-validator, the repository
nlohmann_json is fetched via the fetch_content functionality of CMake.
It is a huge repository with size 180MB, which are downloaded whenever
one configures CMake on an empty build directory (e.g. after deleting the
build directory to clear out cached CMake variables.)
The repository
https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent

only contains releases instead of all development commits and has
(at the moment) size of only 830kB, which stronly cuts the download time.
