Try downgrading config when unknown (too new) version

Cloud Shell users who try our examples hit unknown api version errors for several days after our release as Cloud Shell’s Skaffold installation lags. This isn’t a great experience.

Here are three approaches:

1. What if we tried reloading the config but using our latest known confit? Chances are that most configs will load just fine.
2. What if we stop updating the apiVersion in the examples except when required for new fields it changes?
3. What if we updated the example apiVersions as a separate step once the new version of Shahid has prepared to Cloud Shell and gcloud?
