Fix densenet pipeline: update EOL Docker images and DALI CUDA version

- Update ubuntu20.04 base images to ubuntu22.04 (convert_to_image_directory, apply_image_transformation)
- Remove unnecessary CUDA image from init_image_transformation (CPU-only step, aligned with SDK)
- Fix nvidia-dali-cuda100 -> nvidia-dali-cuda110 to match CUDA 11.8 base image (CLI + SDK)
