use HTMLElement for generic DOM node types (#3169)

We keep specific types for elements with special meaning, such as
`HTMLButtonElement`, `HTMLLabelElement` or `HTMLInputElement` because
they receive certain attributes that generic DOM nodes (such as
HTMLDivElement) don't

For the components where we use simple `div` elements (and where people
use `as={...}`) that renders a different element, it doesn't make sense
to use `HTMLDivElement`. Using a more generic `HTMLElement` is simpler
and more correct (we still had `HTMLUListElement` and `HTMLLIElement`
for "div" DOM nodes which is incorrect).

This shouldn't be a breaking change because an `HTMLDivElement` is still
a valid `HTMLElement`. The other way around wouldn't be the case.
