Reconcile BAZEL and CMAKE dependency on nlohmann-json

[marcalff]

Greetings,

In file bazel/repository.bzl

The BAZEL build uses nlohmann-json version 3.6.1

    # JSON library
    maybe(
        http_archive,
        name = "github_nlohmann_json",
        build_file = "@io_opentelemetry_cpp//bazel:nlohmann_json.BUILD",
        sha256 = "69cc88207ce91347ea530b227ff0776db82dcb8de6704e1a3d74f4841bc651cf",
        urls = [
            "https://github.com/nlohmann/json/releases/download/v3.6.1/include.zip",
        ],
    )

In file third_party_release

The CMAKE build uses nlohmann-json version 3.9.1

nlohmann-json=v3.9.1

At the very least, both builds should use the same version, so an upgrade to 3.9.1 in basel is needed.

Alternately, consider upgrading both to nlohmann-json 3.10.5 (Release date: 2022-01-03)

To avoid future discrepancies, please consider adding maintainer comments in each place,
pointing to the other build scripts.

Regards.
