* [Gatsby docs a11y] Add `aria-label` to search input
**what is the change?:**
See title.
**why make this change?:**
There was no label on this input, and screen readers might not have been
able to identify it's purpose.
[The `placeholder` doesn't count as a label.](http://a11yproject.com/posts/placeholder-input-elements/)
**test plan:**
Manually inspected the HTML in the devtools, and ran the aXe a11y audit
tool, and the warning generated by aXe was gone.
**issue:**

* [Gatsby Docs a11y] Increase contrast of 'installation' page tabs
**what is the change?:**
Change the dark blue used for the text/background of the tabs on the
'installation' page to a slightly darker blue, which we were already
using for the 'focus' style of the tabs. It looked a bit weird before,
imo, when the 'focus' was darker.
Now the 'focus' style just lightens the border to the new signature
blue.
**why make this change?:**
To add enough contrast that folks who see colors differently can still
decipher the writing on the tabs on this page.
We plan to refactor this page and remove the tabs soon, so not too
worried about making this fix perfect.
**test plan:**
Manual testing - loaded the page and it looks ok, and ran aXe a11y
audit, no more warnings about contrast. :)

Adds a new docs website, built with Gatsby JS, to replace the old Jekyll site. Source code for the new site lives in /www (although markdown and YML data still comes from the legacy /docs folder).
Changes to either markdown or website source code can be previewed on Netlify. The react-js bot should automatically add comments to each PR with preview links. (This preview is generated by running the newly-added yarn build:docs command in the root package.json.)
The majority of the changes in this PR are contained within the new /www directory. However some minor modifications have been made to existing content in the /docs directory:
* Modified frontmatter author block to always be an array
* Small markdown formatting tweaks
* [Docs: Installation] Fix tabs responsive layout
* Move tabs a pixel down
* Remove left margin on first tab
* Remove the long line
* Fix mobile styles
* Add tabs to installation page (#9275, #9277)
This adds tabs for create-react-app and existing apps to the installation section of the docs. The tab implementation is a simplified version of React Native's installation page.
Fixes#9275.
* Use classList instead of className
* Use same implementation as in RN
