Use GVK for listing CRDs in a repo

[hasheddan]

CRDs are currently listed by filename. When controller-gen has generated the CRD files this works well as the pattern of the filename is <group>_<plural-kind>.yaml. However, it would be nice to also support files with arbitrary names and potentially present the CRDs in an organized format, such as nesting CRDs under their group and listing multiple versions of the same kind together.

Would it also make sense to group by Group or GroupVersion? In the https://doc.crds.dev/github.com/jetstack/cert-manager view, having the acme.cert-manager.io/v1alpha2 Challenge and Order kinds next to each other would be preferable

Good point @mcristina422! I’ll reopen this and make sure that gets updated 👍
