Update a command to run correctly for a reader (#9167) 

# Issue
The command of jobs does not run correctly if its job already finished.
Some readers may confuse that they can't succeed to run a command to follow this tutorial.
So, we should add `--show-all` option to show pods that may be completed.

# The log to show that we need to add an --show-all option
```
$ kubectl get jobs
