BUG: Custom Core Block Variation details not updated in "Settings Sidebar" section

[deepakvijayan]

Issue:

When adding a custom core block variation, the details ( title, icon, description ) are not updated in the "Settings Sidebar" section. Hence there is no way to distinguish between custom core block variations and core blocks once a block is added.

How to reproduce:

1. Add support for block variations to your existing theme.

function prefix_editor_assets() {
	wp_enqueue_script(
		'prefix-block-variations',
		get_template_directory_uri() . '/assets/js/blocks/block-variations.js',
		array( 'wp-blocks' )
	);
}
add_action( 'enqueue_block_editor_assets', 'prefix_editor_assets' );

2. Create a custom core block variation

wp.blocks.registerBlockVariation(
	'core/group',
	{
	    name: 'card-group',
	    title: 'Card group',
            description: 'A group with card styling',
            label: 'Card group',
            icon: 'wordpress',
            attributes: {
	       className: 'card-group',
            },
            innerBlocks: [
                [ 'core/heading', { content: '' } ],
                [ 'core/paragraph', { content: '' } ],
            ]
	}
);

3. Check inside editor for new core block variation.

4. Add new core block variation and check the siderbar with the block selected.

Attaching pic & screen recording of the issue as well.

Note: I used the following tutorial by Carolina Nymark to create the variation
