Examples should be added for failfast & withParam

[MagicFrogSJTU]

Summary

Before all, I am new to all K8S and argo workflow stuff.
Recently I am struggling with finding solutions for having sequential task pipeline of arbitrary steps. After endless searching on official argo documentation and googling, I finally ended up at: #3644. And that is exactly what I need, failfast & withParam!
I strongly recommend that we have a example for that simple but splendid solution in repos. If authors are currently too busy, I am willing to write it myself.

Use Cases

For those new to argo workflow.
