[TypeScript] Fix TS errors with <ArrayField> and <ChipField> in stories

[slax57]

Fixes errors such as the following in ArrayField.stories.tsx:

Type '{ children: Element; record: { id: number; books: { id: number; title: string; author_id: number; }[]; }; source: string; }' is not assignable to type 'IntrinsicAttributes & { children?: ReactNode; }'.
  Property 'record' does not exist on type 'IntrinsicAttributes & { children?: ReactNode; }'.ts(2322)

Basically, if the children prop type is not exactly the same as what React expects (ReactNode | undefined), the type of the component will be React.FunctionComponent<{}> instead if the declared type (and hence every additional prop is not recognized)
