Description
Sorry, I can't see anywhere mentioning whether this is compatible with 8.1, but after upgrading form 2.4.3, running bin/magento returns
```
bin/magento setup:upgrade
PHP Fatal error: During inheritance of Iterator: Uncaught Exception: Deprecated Functionality: Return type of Migration\ResourceModel\AbstractCollection::current() should either be compatible with Iterator::current(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /magento2/vendor/magento/data-migration-tool/src/Migration/ResourceModel/AbstractCollection.php on line 35 in /magento2/vendor/magento/framework/App/ErrorHandler.php:61
```
I don't think it's a caching error, https://github.com/magento/data-migration-tool/blob/2.4-develop/src/Migration/ResourceModel/AbstractCollection.php is not specifying the return type?

Research direction
Start with src/Migration/ResourceModel/AbstractCollection.php, especially the current() method named in the PHP 8.1 fatal error. Run bin/magento setup:upgrade under PHP 8.1 to reproduce the failure and verify that the command completes without the reported return-type deprecation error.
