Consider removing manual pipeline steps, jumping into Jenkinsfile sooner.

Problem:
I personally question the value of having them do things the bad way first before going into the good way. Especially when it is not a simple or quick thing for them to do so. I also don’t think that there is an analogous thing to translate those steps into if/when we move to Tekton.

Proposed solution:
Remove Ex2 pt3 entirely. Jump directly into using the Jenkinsfile. Also probably move Ex4 pt2 here.
