Small typo in LFS258: V 2018-11-13

In Lab Exercise 6.3: Working with Jobs, step 11 of Create A Job we are instructed to "increase the sleep argument to five":
args: ["5"] #<-- Edit this line
Then in the same lab, step 2 of Create a CronJob the sleep argument is shown to be three:
args: ["3"]
The lab should either ask for an edit to 3, or else show the correct value (at this point sequentially in the lab) of 5.
If there existed a git repository for the labs, I would have submitted a PR instead.
