Subject: [PATCH] Code Modernization: Rename parameters that use reserved
 keywords in `wp-includes/formatting.php`.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit renames the `$class` parameter to `$classname` in `sanitize_html_class()`.

Follow-up to [54927].
