🛠️ Repo: Two-column lists in the docs should not be the default style for lists

[boneskull]

This should not be the default list style:

Change the stylesheet to display a "normal" list unless we apply a specific class for two-column display. I think it's OK to use in some places, but not for all lists.

unless there's a way to specify the class in our markdown compiler (not sure), just use html for the ones we keep. features and table of contents are good to keep... not sure about the rest.

For implementors:

To see changes locally, run npm start docs and open up docs/_dist/index.html with your browser. You can also do npm start docs.watch to rebuild as you work (you'll still have to reload).

would like to take this one. had to reconfigure "wd" module with fresh install to get tests to pass.

@crossaaron the wd module is only used for tests on SauceLabs, which you aren't running locally, so not sure what the problem was there.

at any rate, changes here should not affect any browser tests; the only potential failure would be a linting error.

Hi! I'm new to Open Source and was looking for a good first issue to start contributing. May I give it a try? (#3702)
Thanks in advance!
