Add an extra step to detail Docker environment clean up

[mjbear]

Summary

Add steps to detail cleaning up the Docker environment (stop container, delete image).

These courses are great and offer a low barrier of entry for beginners. Since beginners can work through this course it is a good idea to also include how to stop the Docker container and also remove the image when we're done with it.

Changes

• Adds a Step 6 markdown file
• Modifies the third Actions workflow file to include Step 6 markdown content
• Modifies the Step 1 markdown file to emphasize the cd repo with inline code tags (as seen to the left)
  • (This matches the style convention in later Step markdown files.)

Closes: #47

Task list

• For workflow changes, I have verified the Actions workflows function as expected.
• For content changes, I have reviewed the style guide.

I performed testing via this temporary repo: https://github.com/mjbear/test_skills-publish-packages
(Once this is evaluated and hopefully merged, I plan on deleting that "test" repo.) 😀

Is there an simple way to test the Actions workflow?

(As compared to creating a new branch new_main, merging my feature branch into that, renaming main to old_main, and then renaming new_main to main. And cloning the template repo to manually go through the workflow. And then setting the default repo to be main again. 😅 )

@mjbear Thank you for submitting this PR! ✨

Would it make sense on the X-finish.md step to link to the MS Learn Introduction to Docker containers module?

I'll get this triaged for review, and the team can address this Q from your linked issue during their review 💛

I've been full of PRs lately 🤣 ... yeah, there's a few others against this repo

If you and your team think the MS Learn article would be good to link to, I will add that modification to this PR and y'all can merge away.

Thank you! 💚

I'm curious to learn of any feedback.
