Final preparations for 1.4 (kubeflow#6177)

* Improve README for example-notebook-servers (kubeflow#6165)

* jwa(front): Don't disable vendors with no GPUs (kubeflow#6171)

JWA should not block users from selecting GPUs if the current cluster
nodes do not have any GPUs attached to them. We've seen users that have
autoscaled nodegroups for GPUs, so a GPU node will be added to the
cluster once a Pod has requested it.

   update all the images of our components to the `v1.4` tag
2. Update the VERSION file so that the post-submit script will build all
   images
