Issue description

the output in step 2.6 is slightly different from the real output of the lab.

Steps to reproduce:

Workaround:
Modify the output block to show the 'verify error' line immediately after the 'depth=1' line, before any certificate chain details. Replace the current output block with:

[student@workstation ~]$ oc exec no-ca-bundle – openssl s_client -connect server.network-svccerts.svc:443
depth=1 CN = openshift-service-serving-signer@1667565598
verify error:num=19:self signed certificate in certificate chain
DONE
CONNECTED(00000004)

...output omitted...

verify error:num=19:self signed certificate in certificate chain

Expected result:
