Block Editor: Warning when rendering InnerBlocks

[aduth]

Describe the bug

A warning is logged in development environments when a Columns block (or presumably any block with InnerBlocks) is rendered.

react-dom.8b3dda97.js?ver=16.9.0:539 Warning: React does not recognize the `hasPopover` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `haspopover` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

To reproduce

Steps to reproduce the behavior:

1. Navigate to Posts > Add New
2. Insert a Columns block
3. Open Developer Tools Console and observe warning

Expected behavior

No warnings.

Additional context

Introduced in #19922.

Fix is to avoid applying prop to Container when Container is assigned as 'div'.

Line 74 in 8313c65

const Container = rootClientId ? 'div' : RootContainer;

gutenberg/packages/block-editor/src/components/block-list/index.js

Lines 82 to 89 in 8313c65

	<Container
	ref={ ref }
	className={ classnames(
	'block-editor-block-list__layout',
	className
	) }
	hasPopover={ __experimentalUIParts.hasPopover }
	>
