I don't understand why the bot still mentions missing docstrings, did I not fix them?

[HerHde]

Hey @dwoz, this is ready for review.

As mentioned, I don't quite understand why the PR Bot is complaining. Some pipelines seem to fail while trying to check out the code, so I assume it shouldn't concern me.

If there is anything, please let me know!

Maybe @Ch3LL could help me with this one?

Hi! I'm your friendly PR bot!

You might be wondering what I'm doing commenting here on your PR.

Yes, as a matter of fact, I am...

I'm just here to help us improve the documentation. I can't respond to
questions or anything, but what I can do, I do well!

Okay... so what do you do?

I detect modules that are missing docstrings or "CLI Example" on existing docstrings!
When I was created we had a lot of these. The documentation for these
modules need some love and attention to make Salt better for our users.

So what does that have to do with my PR?

I noticed that in this PR there are some files changed that have some of these
issues. So I'm leaving this comment to let you know your options.

Okay, what are they?

Well, my favorite, is that since you were making changes here I'm hoping that
you would be the most familiar with this module and be able to add some other
examples or fix any of the reported issues.

If I can, then what?

Well, you can either add them to this PR or add them to another PR. Either way is fine!

Well... what if I can't, or don't want to?

That's also fine! We appreciate all contributions to the Salt Project. If you
can't add those other examples, either because you're too busy, or unfamiliar,
or you just aren't interested, we still appreciate the contributions that
you've made already.

Whatever approach you decide to take, just drop a comment here letting us know!
