rule: aria-allowed-children

[WilcoFiers]

This one really surprised me, but there doesn't seem to be a rule that checks that an element is allowed certain children. For instance, the following isn't flagged by Axe:

<div role="listbox">
  <p role="button">button</p>
  <p role="option">option</p>
</div>

@WilcoFiers isn't it the same problem as this old PR intended to solve? #623

[WilcoFiers]

Nope, that rule checks that elements are allowed a certain role. So for instance an h1 isn't allowed to have role=button.

See w3c/aria#1033

This rule is a duplicate of the more recent #2076
