src/meta-openembedded:nlohmann-json: upgrade 3.9.1 -> 3.10.2

Release date: 2021-08-26
SHA-256: 059743e48b37e41579ee3a92e82e984bfa0d2a9a2b20b175d04db8089f46f047 (json.hpp)
61e605be15e88deeac4582aaf01c09d616f8302edde7adcaba9261ddc3b4ceca (include.zip)

Summary
This release is made days after the 3.10.1 release due to a bug in the release script:
The 3.10.1 release at GitHub contained the correct files,
but the associated tag v3.10.1 points to the wrong commit.
This release is made with a fixed build script. All changes are backward-compatible.

Improvements
Fix the release scripts to correctly tag releases. nlohmann/json#2973
Fix some -Wunused warnings on JSON_DIAGNOSTICS when the library is built without CMake.
nlohmann/json#2975
nlohmann/json#2976

Deprecated functions
Passing iterator pairs or pointer/length pairs to parsing functions
(basic_json::parse, basic_json::accept, basic_json::sax_parse, basic_json::from_cbor,
basic_json::from_msgpack, basic_json::from_ubjson, basic_json::from_bson)
via initializer lists is deprecated.
Instead, pass two iterators; for instance, call basic_json::from_cbor(ptr, ptr+len)
instead of basic_json::from_cbor({ptr, len}).
