/area testing
/kind bug

What happened:
I tried to run druid e2e tests locally with make ci-e2e-kind but it fails with this error:

parsing skaffold config: error parsing skaffold configuration file: unknown skaffold config API version "skaffold/v4beta10". Set the config 'apiVersion' to a known value. Check https://skaffold.dev/docs/references/yaml/ for the list of valid API versions. Otherwise, check that your skaffold version is up-to-date.

I also updated my skaffold but still got the same error. I think there are some indentation problem in skaffold.yaml due to which skaffold is unable to parse the druid's skaffold manifest.

What you expected to happen:
Druid e2e tests shouldn't failed

How to reproduce it (as minimally and precisely as possible):
I simply run this: make ci-e2e-kind but I'm not sure how's prow jobs are running fine.
