PHP 8.1 deprecates passing `null` to PHP native functions where the parameter(s) is not explicitly nullable. While in PHP 8.1 this is only a deprecation, it should, of course, still be fixed. This commit contains a fix for the second of the two issues in WordPressCS found related to this so far (based on the unit tests). Passing `null` to `trim()` is now deprecated, so more defensive coding or explicit type casting is needed. This comes into play for the `I18nSniff::process_token()` and the `PrefixAllGlobalsSniff::process_token()` methods where the `Helper::getConfigData()` method can return either string or `null`.
