ui: Fix the cluster version in create node and about page

We couldn't retrieve the cluster version is because we call the
fetchClusterAction before we are authenticated to k8s api.

Solution: since we use the `cluster version` only in create node page
and about page, it makes sense to fetch the data only in those two
pages.
