Bump PHP requirements to PHP 8.1

We are forced to do this because we want to use Twig Components and those require using PHP 8.1.

This should be fine because only 1% of our users still use PHP 8.0 (and ~10% are still in PHP earlier versions): https://packagist.org/packages/easycorp/easyadmin-bundle/php-stats
