Skaffold fails when building with Kaniko on ARM64

Using my Intel Mac, I am trying to build the go-hello-world example with Kaniko running on an ARM64 k8s cluster. It fails, as `gcr.io/k8s-skaffold/skaffold-helpers/busybox` is not an ARM64 image. Is there someway to overcome this?

```
skaffold version
v1.20.0
```
