macOS setup script fails due to missing files folder path

[lisorthman]

When running the macOS setup script (./setup/macos/setup.sh) in the DO100x-apps repository, the script fails with the following error:

sed: ./setup/macos/files/role-binding.yml: No such file or directory
Could not apply security resources

Root cause:
The script expects the role-binding.yml and other files to be in ./setup/macos/files/, but in the repository, these files exist in ./setup/files/.
