Fix GitHub Actions version comments to specify patch versions

Updated version comments to match the actual versions being used:
- actions/checkout: v5 → v6.0.0 (hash was already updated)
- actions/setup-node: v6 → v6.0.0
- actions/setup-python: already correct at v6.1.0
- step-security/harden-runner: already correct at v2.13.2

All actions now have proper patch version comments for better security clarity.
