fix: Fix type for ref prop (#9)

`HTMLProps` is only intended for HTML Elements. `HTMLProps<AnElement>` means `HTMLAttributes<AnElement> & ClassAttributes<AnElement>`

`ClassAttributes<T>` means something has a `ref: string | (instance: T) => any` property.

A component wrapping an element (like ours) should therefore have props extending

* `HTMLAttributes<WrappedElement>` (for the element props it passes on), and
* `ClassAttributes<Wrapper>` (for the ref function `ref={wrapper => ...}`)
