`kubectl explain` is broken for kcp api-resources

[xingxingxia]

Describe the bug kubectl explain is broken for kcp api-resources, e.g. locations, clusterworkspaces, workspaces et al. Works well for other k8s traditional resources, though, clusterroles.

To Reproduce Steps to reproduce the behavior:

1. Login to kcp "stable" service as of this issue is filed

2. Show current ws: $ kubectl kcp ws Current workspace is "root:rh-sso-158xxxx". $ kubectl api-resources

   NAME                              SHORTNAMES   APIVERSION                             NAMESPACED   KIND
   ...
   clusterroles                                   rbac.authorization.k8s.io/v1           false        ClusterRole
   ...
   locations                                      scheduling.kcp.dev/v1alpha1            false        Location
   clusterworkspaces                              tenancy.kcp.dev/v1alpha1               false        ClusterWorkspace
   ...
   workspaces                                     tenancy.kcp.dev/v1beta1                false        Workspace

3. Run kubectl explain for kcp resources to know the description of them $ kubectl explain locations error: couldn't find resource for "scheduling.kcp.dev/v1alpha1, Kind=Location" Checking if verbose output returns more clues: $ kubectl explain locations --v 6

It works well for k8s traditional resources, though, clusterroles: $ kubectl explain clusterroles

   
   KIND:     ClusterRole
   VERSION:  rbac.authorization.k8s.io/v1

DESCRIPTION: ClusterRole is a cluster level, logical grouping of PolicyRules that can be

**Expected behavior**
`kubectl explain` should work well to return description for kcp resources like for k8s traditional resources.

Is there an plan to work on this? I'm seeing this for exported/bound resources and not just the kcp APIs

This should work now since #3118 got merged. @gmrodgers sorry for the late reply. Any chance you can give it a spin and confirm please?

This is how it looks like for me on latest main:

$ kubectl explain workspace
GROUP:      tenancy.kcp.io
KIND:       Workspace
VERSION:    v1alpha1

DESCRIPTION:
    Workspace defines a generic Kubernetes-cluster-like endpoint, with standard
    Kubernetes discovery APIs, OpenAPI and resource API endpoints.
     A workspace can be backed by different concrete types of workspace
    implementation, depending on access pattern. All workspace implementations
    share the characteristic that the URL that serves a given workspace can be
    used with standard Kubernetes API machinery and client libraries and command
    line tools.

The PR mentioned above was included in v0.24.0 and if I didn't misunderstand the issue it should work fine. Closing this.
