text: Title: Many links in API documentation broken
  Body: **What happened**:
  There are many spots in API comments that are broken (pointing to https://git.k8s.io/community/contributors/devel/api-conventions.md). One example is here: https://github.com/kubernetes/api/blob/master/core/v1/types.go#L3491, a quick search for that URL currently shows [84 results on github](https://github.com/kubernetes/api/search?q=https%3A%2F%2Fgit.k8s.io%2Fcommunity%2Fcontributors%2Fdevel%2Fapi-conventions.md&unscoped_q=https%3A%2F%2Fgit.k8s.io%2Fcommunity%2Fcontributors%2Fdevel%2Fapi-conventions.md) (however this is obviously including generated files too)
  
  These lead to broken user-facing doc links, such as in `oc explain` in OpenShift
  
  **What you expected to happen**:
  I'm assuming these are supposed to be updated to https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md
