storybook: [Bug]: In onboarding `background` should be `backgroundColor`

Describe the bug

There’s a bug in the example stories shown during onboarding. It mentions an arg background: "red" but the Button component does not accept a background prop. It does accept backgroundColor.

To Reproduce

Start a fresh Storybook project and follow the onboarding tutorial. At the stage where it shows an example stories file, there’s a story (I think the Primary one) that has the bad prop name.
