Category widget block: Markup structure inconsistent in editor compared to other widgets

[laurelfulford]

Describe the bug
In the editor, the Category widget's list is wrapped in an extra div, with the .wp-block-categories class on it:

<div class="wp-block-categories">
	<ul class="wp-block-categories__list wp-block-categories__list-level-0">
		<li>...</li>
	</ul>
</div>

The other widget blocks just have their respective classes (.wp-block-archives, .wp-block-latest-posts, .wp-block-latest-comments) right on the list element:

<ul class="wp-block-archives wp-block-archives-list">	
	<li>...</li>
</ul>

<ul class="wp-block-latest-posts">
	<li>...</li>
</ul>

<ol class="wp-block-latest-comments has-avatars has-dates has-excerpts">
	<li class="wp-block-latest-comments__comment">...</li>
</ol>

This looks to be related to #9411, where this extra div was removed from the front-end.

To Reproduce

1. In the editor, add a Category block and an archive block (plus any of the other widget blocks).
2. Examine the markup in the editor.

Expected behavior
That the markup structure on the blocks would be similar in the editor.

Additional context
Recreated in Gutenberg 4.6.1, though it's also there in earlier versions.
