Thank you for your contribution! Please make sure that you also change the following files to fix the presubmit failure:

• images/releng/k8s-ci-builder/Makefile
• images/releng/k8s-ci-builder/Dockerfile
• images/releng/k8s-ci-builder/variants.yaml

These files should be updated after updating kubernetes/kubernetes.

The previous error was probably because I accidentally changed the version of the section under dependents.yaml:

 - name: "golang: after kubernetes/kubernetes update"
    version: 1.16.5
 - name: "golang: after kubernetes/kubernetes update (for previous release branches)"
    version: 1.15.13

It has been modified back to the original version.
