Detection of skaffold dev [not run] mode fails with Skaffold 1.13+

https://github.com/Yolean/kubernetes-assert/blob/0a337dcef49606fa413c56f9faf02b254ae23964/runtime-nodejs/kustomize/scrapeable-deployment.yaml#L45 doesn't work anymore.

The labels I see on a new `skaffold dev` deployment is:

```
              app.kubernetes.io/managed-by=skaffold
              skaffold.dev/run-id=c999a4c5-db64-4f1c-9fe5-89f1b68b93fc
```
