Export json_document and json_view from the C++20 module

Browse Source 
The nlohmann.json module includes json_view.hpp in its global module
fragment and exports basic_json_document, basic_json_view, and the four
aliases next to basic_json, json, and ordered_json. features/modules.md
lists them, and tests/module_cpp20 parses a document, so that a missing
export fails the ci_module_cpp20 job.
