Integrate Kubepug for deprecation analysis

[olensmar]

see https://github.com/rikatz/kubepug - I would like to see deprecation notices for my resources (cluster, previews, vanilla, etc) - given the currently selected k8s version for my project

It would be great to be able to compare schemas to see the changes, using the compare all feature with schemas from different versions of K8s. A way to document the changes in API and schemas without having to look for it online, and being able to compare versions that are not adjacent (i.e. my cluster is in 1.21 and I want to see the changes when I deploy 1.24.2), ideally with a report on non-compliant resources in the project and/or cluster
