PHP 8.1 | PassedParameters::getParameters(): document test with named…

… params after argument unpacking

Prior to PHP 8.1, using named arguments after a variadic argument in a function call was a compile error.
As of PHP 8.1, this is now fully supported.

The tests already contained a code sample covering this. The documentation for the test case has now been adjusted.
