Missing doc comment for function add_site_favicon()

	echo '<link rel="shortcut icon" type="image/x-icon" href="' . get_template_directory_uri() . '/assets/images/favicon.png" />';

All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found 'get_template_directory_uri'.
