collectCoverageFrom does not like absolute paths

The `collectCoverageFrom` in itg-react-script's `config/jest.js` uses absolute paths, which doesn't work. As a workaround, you can define this in your local jest.config.js:

```js
module.exports = {
collectCoverage: true,
collectCoverageFrom: [
'src/**/*.{js,jsx}',
],
};
```

Start in config/jest.js and compare its collectCoverageFrom setting with the local jest.config.js workaround shown in the issue. Reproduce coverage collection, then verify the configuration works without requiring absolute paths.
