fix: simplify docker-compose-opengauss.yml configuration

Docker Configuration Optimization:
✅ Simplified OpenGauss Docker setup
  - Commented out volume mounts for easier testing
  - Removed persistent data volume to avoid permission issues
  - Removed custom setup script dependency
  - Maintained core service configuration

✅ Benefits for users
  - Faster container startup without volume setup
  - No dependency on external setup scripts
  - Easier testing and development workflow
  - Reduced complexity for new users

This change makes it easier for users to quickly start an OpenGauss
instance for testing the gaussdb-rust examples without dealing with
volume permissions or custom scripts.
