Allow to use any HTML Element as menu item

The code works with any HTML element, there's nothing that requires
specifically `HTMLAnchorElement` (`<a>`) except `e.currentTarget.href`
which is already conditional. Thus the current limitation is only a
typing issue introduced by unnecessarily specific `ref` type. We can
make it a generic parameter, but it wouldn't bring any real benefit,
just increase complexity and decrease flexibility.

Resolves #174
