Updated jupyter ML interactive tool

[tuncK]

Some ML tasks fail because of old library versions. Updated the versions of the tools contained within the container at https://github.com/usegalaxy-eu/gpu-jupyterlab-docker/pull/2. This PR is necessary to switch to this new container.

For more portability, the container has both CPU and GPU versions of tensorflow installed, and we choose based on presence/absence of GPU during initialization.

@bgruening, docker push action worked and I updated the xml file to pull from quay.io.
