[docs] Upgrade to next 9

[eps1lon]

Preview: https://deploy-preview-18441--material-ui.netlify.com/

• /api moves to /api-docs to not be considered an API route. Via rewrites we keep the URLs
• /static is deprecated in favor of /public
  We can use this to move the /cdn into /public. I didn't touch the static paths since this affects some 300 files some of which are translated.
• Container is deprecated so I removed it
• fixup bundle size tracking of landing page
• how to reproduce bad transpilation
• netlify build time looks the same, azure took 2-3 minutes longer though (would take 10minutes more build time there TBH)

Future work

• reintroduce (and change approach) page size tracking
• investigate if we can remove the custom server.js by using rewrites for i18n Done

Early overview while it's still in draft. Feel free to ignore it.

[eps1lon]

Upgrade to latest stable next release in a follow-up since they changed how they polyfill.

[oliviertassinari]

The only issue I can spot on the live preview is the open side nav on the home page

[oliviertassinari]

Should we try to deploy the branch in production to see how that goes before merging?

Right forgot about that one. Will fix.

Not sure what you mean by production. It's already built for the production environment in the deploy previews.

Awesome, great work!

Not sure what you mean by production.

I had http://material-ui.com/ in mind. So I can run SEO crawlers and tests the locales (e.g. /zh/)

Why can't you do that with the deploy preview?

[oliviertassinari]

@eps1lon I have rebased to resolve the conflict with master, I hope it's fine with you. I think that it's good to land, feel free to merge when you are ready 🚀😄.

[eps1lon]

Let's see if this works.
