explicit path to string conversion for Windows

Apparently an implicit conversion via `=` does not exist on Windows:

D:\a\Soar\Soar\Core\CLI\src/cli_CommandLineInterface.cpp(93): error C2679: binary '=': no operator found which takes a right-hand operand of type 'std::filesystem::path' (or there is no acceptable conversion)

        with
