Link to Docker, about image digests not relevant

[digest](https://docs.docker.com/engine/reference/commandline/pull/#pull-an-image-by-digest-immutable-identifier).

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.

Thanks for the issue.

Folks considering a fix: here's what I recommend.

1. Send in a PR to update the CNCF cloud native glossary to explain image digest.
2. Update the Kubernetes concept page for container images, to link to that new glossary entry rather than to the Docker documentation.

Hey @lmktfy , kindly review this , cncf/glossary#3627

[iacker]

I am working on the Kubernetes website side of this issue now that the CNCF glossary PR is open, by updating the container images concept page to stop pointing readers to Docker for the image digest explanation.

Hello all, I am one of the maintainers of Cloud Native Glossary project (but not representing), and
we are discussing whether to add the term (Container) Image Digest to Cloud Native Glossary project.
(I am not sure whether the term will be added or not.)
