Improve breadcrumb accessibility

Hi,
to improve accessibility you should change the default breadcrumbs like written here:
https://www.w3.org/TR/wai-aria-practices-1.1/examples/breadcrumb/index.html

Example could look like in this filter:

add_filter(
	'rank_math/frontend/breadcrumb/args',
	function( $args ) {
		$args = array(
			'delimiter'   => ' / ',
			'wrap_before' => '<nav class="breadcrumb" aria-label="Breadcrumb"><ol class="breadcrumb__list">',
			'wrap_after'  => '</ol></nav>',
			'before'      => '<li class="breadcrumb__list-item">',
			'after'       => '</li>',
		);
		return $args;
	}
);
