uninstall openebs documentation is incomplete

[n-able-consulting]

The page https://docs.openebs.io/docs/next/uninstall.html appears to be incomplete. While uninstalling openebs and following this page, I still was unable to delete the namespace, because there were some blockdevices left.

I think kubectl get bd should be to the somation?
