Sync Calico CNI images from upstream

[mateoflorido]

Overview

Sync Calico CNI images from upstream to the ghcr.io registry.

Rationale

We have encountered that we hit the rate limits of DockerHub. This pull request mirrors the images we are using in Calico to ghcr.io, allowing the k8s snap to pull them from there instead of DockerHub.

I have checked and all the images are already in the upstream-images.yaml file. Is there anything else you would like to sync from upstream?

Final comment and we're good to go! Nice work!
