Previously, an older version of the katib-ui had been rocked. This commit updates the rock to the current katib-ui, replicating the build defined by https://github.com/kubeflow/katib/blob/v0.16.0/cmd/ui/v1beta1/Dockerfile

Note:

• the version of the frontend-lib pulled here is that specified by the katib repo in the COMMIT file of the upstream repo
• the GOARCH is omitted from building here because upstream also omits this. This might be something to revisit later, or might be something determined in different ways in rocks anyway?

Closes #32
