doc bug: incorrect example of a virtual workspace

[MikeSpreitzer]

Describe the bug

I am still learning about virtual workspaces. I read https://github.com/kcp-dev/kcp/blob/main/docs/content/en/main/concepts/virtual-workspaces.md . I looked at Example 1. I also downloaded and built and ran v0.9.1 of kcp and tried it out, passing -v=6 to kubectl to see the actual HTTP request(s) involved. Following is an example.

(base) mspreitz@mjs12 kcp % kubectl -v=6 get workspaces
I1102 23:59:46.101073   87303 loader.go:374] Config loaded from file:  /Users/mspreitz/go/src/github.com/kcp-dev/kcp/.kcp/admin.kubeconfig
I1102 23:59:46.115086   87303 round_trippers.go:553] GET https://192.168.1.51:6443/clusters/root:users:zu:yc/apis/tenancy.kcp.dev/v1beta1/workspaces?limit=500 200 OK in 10 milliseconds
NAME        TYPE   PHASE   URL
kcp-admin   home   Ready   https://192.168.1.51:6443/clusters/root:users:zu:yc:kcp-admin

This does not compare favorably to Example 1 in that doc, which cites a URL path of /services/workspaces/<org>/personal/apis/tenancy.kcp.dev/v1beta1/workspaces.

Steps To Reproduce

See above.

Expected Behaviour

I expected running code to be consistent with the documentation.
