Fix the linter for C++ files (#7930)

For whatever reason, the super linter seems to think that any file it doesn't recognize is an EDITORCONFIG file. That means all our `cpp`, `hpp`, `h`, `resw`, `xaml`, etc files are going to get linted with different rules than the clang-format ones we already use. 

This PR disables the EDITORCONFIG linter, and has a minimal change to a cpp file to ensure that it's no longer linted by the action.
