When various methods parameters in child classes were renamed to `$item` to match the parent class for PHP 8 named parameter support, most of the methods restored the more descriptive, specific name at the beginning for better readability, with several exceptions for methods consisting only of a few lines. To avoid confusion about why some methods do that and some don't, this commit aims to bring more consistency to the code, specifically in list tables' `::column_default()` methods. Follow-up to [51728], [51737], [51786]. See #58831. Built from https://develop.svn.wordpress.org/trunk@56586 git-svn-id: http://core.svn.wordpress.org/trunk@56098 1a063a9b-81f0-0310-95a4-ce76da25c4cd
