CI builds on MacOS using compiler.cppstd=gnu98 and failing

[cqc-alec]

It looks like this must be due to a change in conan 2.0.11.

Build logs before conan 2.0.11:

Found apple-clang 14.0
apple-clang>=13, using the major as version

Build logs with conan 2.0.11:

The error is:

 ERROR: There are invalid packages:
nlohmann_json/3.11.2: Invalid: Current cppstd (gnu98) is lower than the required C++ standard (11).

Possibly due to conan-io/conan#14578 .
