Update doc site to handle typescript files

[brandongregoryscott]

Overview Resolves #1607

This PR updates the doc site to not crash when parsing *.tsx files (the build would still succeed anyway, but probably not good to leave it like this). There is a filename option in react-docgen that helps it resolve the babel config which resolves the main issue in #1607.

While I was in here, I also cleaned up the types in PropsTable and tested out to see how it parses TS definitions. I think we may need to tweak the config for components down the line since they are composed on top of ui-box - it seems to only parse top-level props as shown below.

Screenshots (if applicable)

export type ButtonProps = PolymorphicBoxProps<'button', ButtonOwnProps> & {
  onClickFoo?: () => void;
};
