feat(install): enhance script with choice functions and logs

- Added custom `choice_info`, `choice_warn`, and `choice_fatal` functions for interactive input logging.
- Adjusted Docker volume creation message for better clarity.
- Included NVIDIA driver check log for improved feedback to users.
- Added consistent logging before starting LocalAI Docker containers across configurations.
