Refine: Silently skip GMA secrets in restore_secrets.py
d88acfb 
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.
@google-labs-jules
Ensure restore_secrets.py skips GMA paths
1159716 
This commit ensures that `scripts/gha/restore_secrets.py` correctly
skips processing for any GMA-related encrypted files. The existing
check `if api == "gma": continue` should prevent attempts to write
decrypted secrets to the `gma/integration_test` directory, which no
longer exists after the removal of the GMA SDK.

This submission is to confirm the CI tests against this version of the
script.

Fix: Strengthen GMA skip logic in restore_secrets.py
efc5065 
This commit further refines `scripts/gha/restore_secrets.py` to prevent
attempts to write to the deleted `gma/integration_test` directory.

Changes include:
- Initializing `dest_paths` as an empty list.
- More careful construction of `dest_paths` based on whether `FLAGS.artifact`
  is set, ensuring that GMA paths are not inadvertently created.
- Explicitly continuing the loop if no valid destination path is determined
  for a file, preventing unnecessary decryption or write attempts.
- Adding redundant checks to ensure GMA paths are not processed before file
  write operations as a final safeguard.

This should robustly address the `FileNotFoundError` previously observed in CI.
