Link to Docker, about image digests not relevant

https://github.com/kubernetes/website/blob/c43957b9ecb8d2c29a1678ce3994e3a95b013e53/content/en/docs/concepts/containers/images.md?plain=1#L95

link here is irrelevant to what's being discussed, documentation talks about pulling the image digest from the registry. while the link points to "how to pull container image with an image digest".

I'd expect a link that shows how someone would retrieve container image's digest from docker registry, instead of how to download a container image from docker registry with image digest.
