Provide repo level settings for prettier to prevent overwriting of code standards

[jpvajda]

As a vsCode + Prettier user, I find there are certain "opinionated" rules that Prettier enforces that differ from our code standards.

• We prefer * instead of - for our markdown bullets
• We prefer " instead of ' for our quoting
• Could be others that I haven't come across yet.

Given the popularity of prettier in the JS community, perhaps we can add a .prettierignore file to our repo to ensure we don't let prettier overwrite our standards. I spent about 1.5 hours trying to get Prettier to not overwrite the bullets to - and the only solution I found was to disable it in VsCode as a lot of our markdown is in MDX files.

It's possible we could just add settings to our settings.json file for vscode.

@StephenBarlow Since we discussed this issue, I filed an issue for it.

I love the idea of a .prettierignore file!

@benjamn awesome! I was curious to hear your thoughts. 😄 I'll work on this and get a PR up for review.
