Fix two errors in Dockerfile

First error is from Ubuntu cuda GPG error "public key is not available": https://github.com/NVIDIA/nvidia-docker/issues/1632#issuecomment-1112667716.
Second error is from setup.py requiring README.md but Dockerfile does not copy README.md into the docker image.
