The use of Twig_SimpleFilter in /src/Twig/Extension/FieldValueExtension.php is deprecated and should be replaced with Twig\TwigFilter.
Twig_SimpleFilter was deprecated in Twig 2, and is no longer available in Twig 3, which is used in Drupal 10. The new class is available also in Twig 2, and is a simple replacement of the class name, as the Twig_SimpleFilter in Twig 2 is an alias of TwigFilter.
Likewise, the Twig_Extension has been deprecated and replaced with Twig\Extension\AbstractExtension
