bc4a75: Pass example 6 no longer passing in ARIA 1.2

https://act-rules.github.io/rules/bc4a75

Pass example 6:

<div role="list">
	<span role="listitem">Item 1</span>
	<div role="group">
		<span role="listitem">Item 2</span>
		<span role="listitem">Item 3</span>
	</div>
</div>

ARIA 1.1 allows a group child for list: https://www.w3.org/TR/wai-aria-1.1/#list ARIA 1.2 DOES NOT allow a group child: https://www.w3.org/TR/wai-aria-1.2/#list

Should Pass 6 be removed? Or should it be changed to other roles?

Looking into this. Not sure if we need this to become a failed example... TBH. This is the PR where it's changed in ARIA: https://github.com/w3c/aria/pull/1053
