feat: allow Behat 4.x-dev and Symfony 8 alongside Behat 3 / Symfony 5–7

Widen behat/behat to ^3.0 || 4.x-dev@dev (Behat 4 branch supports Symfony 8;
stable Behat 3 does not). Widen symfony/* to include ^8.0. Set minimum-stability
stable with prefer-stable so default resolution stays on tagged releases.

CI: add PHP 8.4 job with Symfony 8.0.*, pinning behat/behat:4.x-dev before
Symfony constraints (PHP 8.4+ required by Symfony 8).
