Ah yes, the joy of the Magento migration tool, immediately breaking your fresh Magento upon installation...

I've created this patch: php8.4-compatibility.patch

Use the cweagans/composer-patches to apply the patch; place it in the patches/composer/magento/data-migration-tool folder and add something like this in your composer.json:

        "patches": {
            "magento/data-migration-tool": {
                "PHP 8.4 compatibility": "patches/composer/magento/data-migration-tool/php8.4-compatibility.patch"
            }
        }
