Add info on where posts are published to

[szunami]

When following this tutorial, I found it very difficult to actually view the post I just created.

The default behavior is documented here: https://jekyllrb.com/docs/front-matter/#predefined-global-variables

Why:

When creating my first post, I found it very difficult to view the post on my published site. I imagine this is a pain point for others.

I opened #1933 to discuss this.

What's being changed:

This PR adds a reference URL where posts are published to.

Check off the following:

• All of the tests are passing.
• I have reviewed my changes in staging. (look for the deploy-to-heroku link in your pull request, then click View deployment)
• For content changes, I have reviewed the localization checklist
• For content changes, I have reviewed the Content style guide for GitHub Docs.
