**What's the problem this PR addresses?**
A decent amount of the examples don't have a `name` field in `package.json` that matches their folder name, meaning they either lack a name or the names are duplicated.
I was testing Yarn 2 workspaces using the entire examples directory and needed to get rid of the duplicates.
**How did you fix it?**
Updated the names to match the names of their folders
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.
