Updated the incomplete data basics repo to reflect the GB handbook how-to guide

[dgwyer]

The data basics app on this repo was incomplete so I went through the handbook guide from start to finish and created the app from scratch.

I've also updated the how to guide via a separate PR: WordPress/gutenberg#43633

This. Is. Awesome! ❤️ It would be great to lint it to make the checks pass. I confirmed this compiles and looks good at the first glance. I'd like to test it in the browser after the linting just to be triple sure the tutorial gave all the right directions.🤞

@dgwyer to lint the code examples I had to:

1. Install the dependencies with yarn --ignore-engine install (npm install didn't work for me)
2. Manually install the eslint plugin like yarn --ignore-engines add @wordpress/eslint-plugin@latest (cc @ryanwelcher )
3. Run npm run format:js

I pushed the changes generated in step 3 to #235 in 3e0acb7

Note the CI still fails – I think it's broken for the entire repo at the moment and it's okay to ignore it for this particular PR.

I could merge #235 with you as the author, or you could add linting to this PR (#227) – whichever you prefer.

@ryanwelcher just merged #235 which includes this plus the linting changes
