Upgrade to Docusaurus 2 (facebookarchive#2268)

Summary:
**Summary**

Fixes facebookarchive#2261. This should be merged after facebookarchive#2267 (how I wish there were stacked diffs on GitHub)

Migrate the website to Docusaurus 2 which provides the following benefits specific to Draft.js:

- Consistency with the other FB Docusaurus websites
- Easy way to import Draft.js (bundle via webpack, no more ugly client-side script tags)
- Nicer CSS framework
- Dark mode (disabled for now until I sort out the dark mode styling for the editor)

Changes made:

- I also changed the theme color of Draft.js to be lighter brown so that the contrast is better in general (much better on dark mode). Let me know if this is not ok.

**Test Plan**
