include nlohmann/json_fwd.hpp in core source headers (#32294)
the file was manually added later to the installted headers, but not on mac

it is not possible to install a file in a Headers subfolder within a framework if the original header is not in the same cmake current directory

installing a header in a subdirectory is achieved by setting the MACOSX_PACKAGE_LOCATION property of the source file
but setting a property can only be achieved if it is in the same cmake directory (from the docs: Source file properties are visible only to targets added in the same directory [0])
