Enrich discover --verbose command tree output with additional data (Layers, data from Descriptor)

[bedla]

WIP

Hi, when I was investigating why Trivy does not see SBOMs attached to Harbor Images (it was because old Harbor v2.10.2 was malformes ArtifactType of attached SBOM JSON. It always override to application/vnd.oci.empty.v1+json. In latest version of Harbor it is fixed), I found out that it is good to see (at that time only in debugger) some additional data about Images. What helped me, was to see MediaType from Descriptor, and MediaType from Layers.

What do you think about those additions to --verbose mode of discover command?

Thank you

Did you want to reopen this?

I would like to, but what I understand from feedback, I should wait for approval of structure that I proposed, right?
