PHP 8.1 deprecations

[someniatko]

I use psalm/phar 4.23.0

When running on PHP 8.1 I get the following output:

PHP Deprecated:  Return type of HumbugBox383\KevinGH\RequirementChecker\RequirementCollection::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in phar:///var/app/vendor/psalm/phar/psalm.phar/.box/src/RequirementCollection.php on line 15
