Type checking of props

[DanWebb]

Typescript isn't checking the validity of props.

This causes issues where storybook examples can use invalid props and errors leak out into projects.

Example with the slider component

In the project we get an error for invalid props:

In the story no error is present:

We can even pass a typed prop using a completely incorrect type without receiving an error:

I've played around with the 3 tsconfigs and compared against the setup in the project but haven't been able to get to the bottom of it.

This SliderProps also extends FormControl which has a [key: string]: any; so it should have never errored on the id but it doesn't make its way into the export.

The props issue is:

1. The path for the Slider component isn't relative (src/ instead of ../)
2. forwardRef uses Pick with keyof Props under the hood which completely messes up the type when [key: string]: unknown is present
