Shortcode for Theme URL

Create a shortcode so I can reference the theme URL within the wp admin

// Add Shortcode
function site_theme_uri() {

	    $theme_uri = is_child_theme()
	        ? get_stylesheet_directory_uri()
	        : get_template_directory_uri();
	
	    return trailingslashit( $theme_uri );

}
add_shortcode( 'theme-images', 'site_theme_uri' );
