Hi @karlkfi
We need to update the Go version in the Kustomize repo before updating it in CI.

And, We need to do more work to update the go version.
kubernetes-sigs/kustomize#5187

We can't update Go in the kustomize repo until CI is updated, otherwise this presubmit fails and the PR merge is blocked.

I've got all the other presubmits passing in kubernetes-sigs/kustomize#5535
