magento2: Zend_Validate_File_Upload - undefined class on 2.4.6

Preconditions and environment

• Magento OS 2.4.6
• method \Magento\ImportExport\Model\Source\Upload::uploadSource is using a removed Zend_Validate_File_Upload class
• restricted_classes.php is missing replacement for Zend_Validate_File_Upload , see: magento-coding-standard/Magento2/Sniffs/Legacy/_files/restricted_classes.php

There is Laminas class which can be used as template for appropriate Magento class: Laminas\Validator\File\Upload

Steps to reproduce

I was digging in the importer code and just found that this class has not been migrated. Uploading an import file larger than configured in php.ini will crash the validator.

Expected result

• restricted_classes.php should have replacement for Zend_Validate_File_Upload , see: magento-coding-standard/Magento2/Sniffs/Legacy/_files/restricted_classes.php

• One of the messages is printed: __('Make sure your file isn\'t more than %1M.', $maxImageSize); __('We can\'t provide the upload settings right now.');

Actual result

Validator crashes
