[react-tracking] Add types for useTracking hook

[damassi]

Updates types for react-tracking@7.0.0, which includes a new useTracking hook. In support of this, TrackingProp now accepts a a generic, which allows us to restrict what props are passed into tracking.trackEvent().

Example:

interface Trackables {
    page: string;
    app: string;
}

 const App = track()((props: { foo: string }) => {
    const tracking = useTracking<Trackables>();

    return <div onClick={() => {
        tracking.trackEvent({
            page: 'Home'
        });
    }}/>;
});

• Use a meaningful title for the pull request. Include the name of the package modified.
• Test the change in your own code. (Compile and run.)
• Add or edit tests to reflect the change. (Run with npm test.)

If changing an existing definition:

• Provide a URL to documentation or source code which provides context for the suggested changes: Add new useTracking React hook nytimes/react-tracking#124
• Increase the version number in the header if appropriate

This doesn’t allow typing the function without using it, which means we’d need a wrapper function just to restrict it by default to our schema, but we can follow up with that in a later PR.
