fix js tests on local

[ashfame]

On my local, in trunk branch, I couldn't run tests (despite clearing node_modules dir and with a fresh npm install), was getting this error:

npm run test

> test
> jest --config=jest.config.js

ReferenceError: module is not defined in ES module scope
This file is being treated as an ES module because it has a '.js' file extension and '/Users/ashfame/git/try-wordpress/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.

With the change in this PR, it worked again. Not sure how it's working in Github actions. 🤔

Thanks! The file was renamed when I changed the type to module in package.json, but I forgot to edit it here.

Currently the tests aren't running on CI yet. I guess we should do that eventually but currently there are no actual tests. The test setup came for the patterns-everywhere repo, but we haven't been writing tests yet.

Gotcha! I was just following the readme and ran into it :)
