The latest version of babel-jest doesn't require `babel-core` with the bridge version anymore (updated in this PR : https://github.com/facebook/jest/pull/7016).
So I'm updating with-jest and with-jest-react-testing-library examples accordingly.
I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:
```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```
This PR contains the result against the examples folder.
This example show how you can test Next.js apps with [react-testing-library](https://github.com/kentcdodds/react-testing-library).
This library encourages your applications to be more accessible and allows you to get your tests closer to using your components the way a user will, which allows your tests to give you more confidence that your application will work when a real user uses it. And also, is a replacement for enzyme.
