When running inside a php 8.1 project a PHP Fatal error regarding deprecated functionality is thrown

[peterschriever]

While working on getting a php 8.1 magento project installed I encountered the following error. This happened as a result from the command: magerun2 env:create and happened before any user input was given. No app/etc/env.php file existed when running the command and none were generated.

PHP Fatal error:  During inheritance of ArrayAccess: Uncaught Exception: Deprecated Functionality: Return type of Elgentos\Dot::offsetExists($key) should either be compatible with ArrayAccess::offsetExists(mixed $offset): bool, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /data/.n98-magerun2/modules/elgentos-addons/src/Elgentos/Dot.php on line 510 in /data/limburgia/magento2/vendor/magento/framework/App/ErrorHandler.php:62
