PR #1165 introduced a new PHP 8.0 related sniff. This sniff has not been in a released version of PHPCompatibility yet.
Variadic parameters are optional by nature. They also MUST be declared last in the parameter list and this requirement has been in place since their introduction.
In other words: variadic parameters should be ignored completely for the purposes of this sniff.
Includes unit tests.
