v1-8-branch.kubeflow.org, from the versions dropdown, doesn't resolve

[chalin]

The Kubeflow version menu contains a v1.8 entry (and v1.8 was release Nov 1), but the link's host doesn't resolve (https://v1-8-branch.kubeflow.org/):

$ curl https://v1-8-branch.kubeflow.org/ 
curl: (6) Could not resolve host: v1-8-branch.kubeflow.org

@zijianjoy I believe this is done through a CNAME DNS record (check the older branches for reference.

Although part of me thinks that we actually shouldn't have cut the v1.8 branch yet, as we usually just leave the latest version as master.

Because we often continue updating the docs after the release, users will get confused if we have a version 1.8 branch, that is actually out of date.
