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]. Props jrf, aristath, poena, justinahinon, SergeyBiryukov. See #55327.
