Add missing parameter to Phar::getMetadata()

[villfa]

Hi,

An new parameter $unserializeOptions has been added in PHP 8.0 to Phar::getMetadata() and PharFileInfo::getMetadata() (see php/php-src@0c238ede0).

Documentation:

• https://www.php.net/manual/en/phar.getmetadata.php

What issue are you trying to solve? Looks to me that it works correctly: https://phpstan.org/r/9509b605-9911-480e-a0d7-ac08b103bd9b

I've got a false positive with Psalm ( vimeo/psalm#7486 ), and since PHPStan had the same flaw in the declaration of the PHP8 delta, I assumed it should be fixed too.

Sorry for not having double-checked before, and for the noise.
