example-intro page provides an example using old version of msw

[skondrashov]

Describe the bug The "full example" at https://testing-library.com/docs/react-testing-library/example-intro imports rest from msw, which is not exported by the latest version of msw (2.1.7).

To Reproduce

1. Go to https://testing-library.com/docs/react-testing-library/example-intro
2. Use the Full Example to set up a test in your own project
3. Realize that you don't have msw installed
4. npm i -D msw
5. Get Module '"msw"' has no exported member 'rest'. error

Expected behavior No errors on the import {rest} from msw line

Additional context I'm guessing the documentation was written when rest was a thing, now http appears to have replaced it.
