* PHP 8.3 | ZipDownloaderTest: fix deprecation notice
Calling `ReflectionProperty::setValue()` with only one argument (to set a static property) is deprecated.
Passing `null` as the first (`$object`) parameter will work cross-version.
As the `ZipDownloaderTest::setPrivateProperty()` method has a `null` default value for the `$obj` parameter anyway, this means the if/else toggle can be removed.
