Image Block - include medium large attachment size

[diggeddy]

Description

GB Image block has same behaviour as core block and omits the medium_large attachment size. It seems WP like to leave it out. But it can be added using this filter:

add_filter( 'image_size_names_choose', function() {
	return [
		'thumbnail'    => __( 'Thumbnail', 'textdomain' ),
		'medium'       => __( 'Medium', 'textdomain' ),
		'medium_large' => __( 'Medium Large', 'textdomain' ),
		'large'        => __( 'Large', 'textdomain' ),
		'full'         => __( 'Full Size', 'textdomain' ),
	];
} );

Is it possible to make the GB image block list other sizes without using the filter ? Even if only the Medium Large is listed

@diggeddy currently, this is a limitation from core itself as they hard-coded the sizes. I'm pushing this for next version so we can implement our own solution.
