Update Docusaurus to 1.3.3 (#1797)

Summary:
Docusaurus 1.3.0 brings about some [backwards-incompatible CSS changes](https://github.com/facebook/Docusaurus/blob/master/CHANGELOG.md#breaking-changes). So the team is helping the major users update 😄

The header font weights in Docusuaurs have been changed to bold, so I removed the custom styling that made it bold. Additionally, I made `<a>` have a different color because the primary color in Draft.js is black and users can't easily distinguish it from body text - bad for accessibility.
