Migrate RSK to "Redux Toolkit"

[markerikson]

Following up from #246 :

Tasks

• New redux-toolkit.js.org domain name
  • Ask for instructions on handling the switch ( Upcoming package rename: Redux Starter Kit -> Redux Toolkit js-org/js.org#3532 )
  • Follow steps for changing over
  • Ensure new redux-toolkit.js.org name points to the site
  • Ensure current redux-starter-kit.js.org name redirects or points to the new site
• Publish the new package name
  • Rename package in package.json
  • Rename Github repo
  • Change URL of repo
  • Update README
  • Update UMD global variable name to RTK
  • Publish new version
  • Merge in new docs site
• Force people to migrate to the new package
  • Publish updated version of RSK that throws an error and prints a "Please migrate..." message
  • Deprecate RSK versions ( https://docs.npmjs.com/deprecating-and-undeprecating-packages-or-package-versions )
• Update docs content
  • Rewrite all the docs content to scrub and update the package name, the actual name, and the abbreviations
  • Re-create / update tutorial sandboxes and repos using new package name
• Come up with a single "sales pitch" description line. I've been using multiple variations in different places, and it would be nice to have something short, descriptive, and consistent.
• Update other Redux docs
  • Redux core docs (front link and content)
  • React-Redux docs (front link)
• Update other content
  • Update title and content of my own blog post: https://blog.isquaredsoftware.com/2019/10/redux-starter-kit-1.0/
  • Go search for other discussions of RSK and rename if possible
• General announcements

I'd recommend using npm deprecate rather than throwing an error, as the package manager will be able to deal with the warnings at build time and the data will be machine readable.

Also, should we add the "formerly known as Redux Starter Kit" to the home page? I feel like people could be mislead by the new site branding and think it's unrelated.

I did npm deprecate as soon as I published RTK for the first time. React Testing Library did the "publish a new version with an error message" thing, so there's precedent. (I think they specifically did it as a major for react-testing-library, which is probably the nicer way to handle it.)

https://redux-starter-kit.js.org still exists as a domain name, but it points to the same Netlify server, so I would hope that would kind of be a clue :)

Just published RSK 2.0, which removes all the code and throws the "migrate to RTK" error message:

https://github.com/reduxjs/redux-toolkit/releases/tag/v1.0.4

That wraps things up here.
