Yes. However, the change only adds a mirror as an additional apt source. The original repositories remain untouched, so it works as a fallback. Also, the mirror is only added when the base image is Ubuntu, so non-Ubuntu base images are not affected. |

What changes were proposed in this pull request?
Similar to #55389, this PR adds ubuntu mirror repositories to K8s Dockerfiles for redundancy.
mirrors.edge.kernel.org seems sufficiently public and reliable.
Why are the changes needed?
Sometimes, ubuntu repositories including archive.ubuntu.com and security.ubuntu.com are very slow, causing
docker buildfailure.We saw such failure on GA.
