Initial Linting Config

[lyleschemmerling]

If I did this right this will check the following:

• Astro files
• Javascript files
• Typescript Files
• Markdown files
• MDX files

With a handful of default rules and a special "no html in the markdown" rule.

✖ 5909 problems (5909 errors, 0 warnings)
  402 errors and 0 warnings potentially fixable with the `--fix` option.

Would like some feedback on the rules before anyone starts trying to fix it.

to try it out:

cd astro
npm run lint

Pretty cool. I'd suggest fixing as many of the errors as you can (or exempting them) before merging.
