Incompatible with Symfony 7.1

[RobertMe]

Hi,

When trying to update to Sulu 2.6.4 and Symfony 7.1 I'm running into a rather awkward situation. When just updating sulu/sulu symfony/* composer prevents the update. This is due to "sulu/web-twig v2.5.6 conflicts with symfony/property-access v7.1.1.". Additional "fun fact" is that this conflict has only be declared in version 2.5.5+ of this package (by #45), meaning that a plain composer update (or composer update sulu/* symfony/*) will happily downgrade this package to 2.5.4 which doesn't have this conflict defined yet. But assuming that the conflict was declared due to some incompatibility it is my believe that with a downgraded version of this package that incompatibility will still be present (+ downgrading obviously means that the bugfixes of later versions of this package are not applied anymore).

I recently upgrade a project to sulu 2.6.4 and experience this problem as well. More importantly, it crashes when using twig 3.12
