Code Modernization: Rename parameters that use reserved keywords in `wp-admin/includes/class-wp-importer.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 `$string` parameter to `$text` in `WP_Importer::min_whitespace()`.

Follow-up to [52946], [52996], [52997], [52998], [53003], [53014].
