In order to follow a consistent style when declaring arrays, the `trailing_comma_in_multiline` rule should be added to the .phpcs.xml file in CheckUser, so that it is enforced by the checks performed when submitting patches to Gerrit. A priori, we wan the rule to only apply to arrays (i.e. the default value for the PHPCS `elements` configuration option). - [Initial thread in Gerrit leading to this task](https://gerrit.wikimedia.org/r/c/mediawiki/extensions/CheckUser/+/1189222/comment/4899c6b2_03da8f79/) - [PHPCS docs](https://mlocati.github.io/php-cs-fixer-configurator/#version:3.87%7Cfixer:trailing_comma_in_multiline)
