Description of problem:
the VERSION of 'oc get node' is not correct.
for ocp 4.8, it should be 1.21.4, but now is 1.21.1. 

from https://docs.google.com/document/d/1Ac1LDNXd_BDgSduoLth_hMGqhd2P8CFpRrJjsaVsH8Q/edit#, it says: "Other z-streams are also affected, maybe with less consequences:
4.8: go.sum k8s.io/kubernetes v1.21.1, but we are on 1.21.4
4.7: go.sum k8s.io/kubernetes v1.20.0, but we are on 1.20.10"

Version-Release number of selected component (if applicable):
4.8.19

How reproducible:
always

Steps to Reproduce:
1.$ oc get node 
NAME              STATUS   ROLES    AGE   VERSION
compute-0         Ready    worker   62m   v1.21.1+6438632
compute-1         Ready    worker   62m   v1.21.1+6438632
control-plane-0   Ready    master   73m   v1.21.1+6438632
control-plane-1   Ready    master   73m   v1.21.1+6438632
control-plane-2   Ready    master   73m   v1.21.1+6438632

2.$ oc version 
Client Version: 4.5.2
Server Version: 4.8.19
Kubernetes Version: v1.21.4+6438632

Actual results:
1. the VERSION is v1.21.1+6438632

Expected results:
