Refine: Silently skip GMA secrets in restore_secrets.py

This commit removes the explicit print statement when skipping GMA-related
encrypted files in `scripts/gha/restore_secrets.py`. The script will
now silently ignore these files, aligning with the complete removal of
the GMA SDK and avoiding unnecessary log output.
