Update package.json to use craco instead of react-scripts

(update storybook port number as per your settings)

{% code title="ui/package.json" %}

```
...
  "scripts": {
    "start": "craco start",
    "build": "craco build",
    "test": "craco test",
    "eject": "craco eject",
    "storybook": "start-storybook -p 6006 -s public",
    "build-storybook": "build-storybook -s public"
  },
