* Updating hapijs package name
Hapi was moved to a new module under the name @hapijs/hapi.
Right now installing just as hapi is giving you this warning:
```bash
npm WARN deprecated hapi@18.1.0: This module has moved and is now available at @hapi/hapi. Please update your dependencies as this version is no longer maintained an may contain bugs and security issues.
```
This change does not affect the integration with next and it continues to work great.
* Update package.json
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.
