Add support for new element types to be used as menu items

[corymharper]

Currently only HTMLAnchorElements are supported for use as menu item elements with the hook. For flexibility, and as not to prescribe the implementation of the hook to developers using the package, making the ref's typing more generic but still type safe would be a warranted enhancement.

This will probably require an addition of passing generic types to the hook in order to accomplish.

Similar to #69.

👍, a good use case for this is handling elements like react-router's Link that wrap anchor tags.

Actually, because Link just renders an anchor, that's mostly moot here. But here's a different use case: menu items could be used to trigger form submission (e.g., see the log out action in this Remix example: https://remix.run/docs/en/v1/tutorials/jokes#build-logout-action -- you'll need to expand jokes.tsx).
