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.
Docker Multistage
* Remove `devDependencies` from `./node_modules`
in `builder` for faster copy on `base` init
* Added `isomorphic-unfetch` to show it not
being copied over to `base`.
* `isomorphic-fetch` will still show from `next`
