fix: remove VOLUME declaration to prevent anonymous volumes

- Remove VOLUME directive that was creating anonymous volumes
- Keep directory creation (mkdir) for runtime mount points
- Users must explicitly mount volumes with -v flags
- This prevents hidden volume bloat in docker exec

Usage:
  docker run --gpus all -p 8053:8053 \
    -v /home/yoge/.cache/modelscope:/root/.cache/modelscope:ro \
    -v /home/yoge/.cache/huggingface:/root/.cache/huggingface:ro \
    -v /home/yoge/.paddlex:/root/.paddlex:ro \
    doc_processer:latest
