fix: correct import comment in statuswait.go from v3 to v4

The import comment in pkg/kube/statuswait.go still referenced
helm.sh/helm/v3/pkg/kube while all other files in the package
correctly reference helm.sh/helm/v4/pkg/kube. This mismatch
causes downstream processing errors (e.g. kythe) when vendoring
Helm.

Fixes #31846
