Add image/information to our dockerhub repo

[sambhav]

Description

The Cloud Native Buildpacks Docker Hub repos (buildpacksio and (cnbs)(https://hub.docker.com/u/cnbs)) look pretty sketchy. cnbs is understandable, given that it seems like we only host sample/internal images (though we do reference it in our docs), but given that buildpacksio is a bit more external (we will soon be referring to it in our tekton task (tektoncd/catalog#434), and it is our "official" lifecycle/pack image), we should probably spend some effort making it a bit more trustworthy.

Proposed solution

Add a description/logo to buildpacksio/pack

Is there a way I can work on this without having access, or is the issue for maintainers?

[sambhav]

This issue can currently only be fixed by maintainers. @samj1912 to figure out a label to tag such issues in the future.

FWIW the information for the lifecycle is referenced here: https://github.com/buildpacks/lifecycle/blob/main/IMAGE.md (we wanted it to live in GitHub so that fixes/changes could be submitted by the community).

I could imagine that a contributor might be able to PR the text to a file in the pack repo and then a maintainer could copy it over.

With that said I'll mark this as ready, but @buildpacks/platform-maintainers please re-label if I'm wrong.
