[local-preview] Differentiate btw Gitpod starting and running

Currently, It takes a while before Gitpod is ready even though
the status says `Gitpod is running` as its not checking for
readyness.

This PR updates the output to separate btw `starting` and `running`.
`Gitpod is running` message is showed only when we see that
the `gitpod-telemetry-init` job has run which happens when
all pods are ready.
