Migrate Website to Docusaurus 2 Alpha

[yangshun]

Hi there! The Docusaurus team is currently developing Docusaurus 2 and are almost done with an MVP that doesn't include translations features, which means there's feature parity with your website's current usage of Docusaurus.

Docusaurus 2 brings about many improvements:

• Client-side rendering with prerendering (site renders without JavaScript!)
• More flexible appearance - Customizable layouts, CSS modules, etc
• Embeddable interactive React components within markdown via MDX

I will be helping you migrate and be the POC throughout the migration process. Let me know what you think!

This looks exciting! Looking forward to enabling you 👍 What support do you need from us?

Just need reviews and helping to test out when it's done. I'll start on it, thank you!
