Fixes #5224
Introduces Linaria as the way to support CSS in JS, because it's the most feature rich option (including TypeScript support).
See this comment for the value proposition.
I got this working in my local dev environment by making these changes directly in my node_modules/react-scripts
folder. I followed up with npm run build
to see if it worked there too and there were no visible issues. A screenshot would be useless, because it looks exactly the same as a standard CRA home page.
