this is just checking props, would it be better to check that there's a context object? otherwise you wont' get the warning sometimes
you could pass the context to retrieve instead of props
useWarnIfNoStyles('Heading', HeadingContext);then in the hook,
useContext(Context)and just check if that returns an object at all
