Update rule aria-required-children

[jeeyyy]

Expectation:
For examples below, the rule should fail because required children role is not correct.

<div role="list">
	<div role="tabpanel">
		<div role="listitem">List item 1</div>
	</div>
</div>

<div role="list" aria-owns="item"></div>

<div id="host"></div>

<script>
	const host = document.querySelector('#host')
	const root = host.attachShadow({ mode: 'open' })
	root.innerHTML = '<div id="item" role="listitem">List item 1</div>'
</script>

Actual:
The rule only looks for children with an allowed role, without intercepting nodes in between which can have over-ridding roles.

Motivation:
Required for implementation of rule in ACT Rule - https://act-rules.github.io/rules/bc4a75

Verified with latest axe-core, and with the above specified test example, aria-required-children rule is failing , which is expected.
