throwing syntax error when the matches regexp is not valid

[WebMamba]

During the symfony live, Fabien talk about a PR he did on the Expression Language component (https://github.com/symfony/symfony/pull/45875/files). The goal was to throw a more readable error when using the matchs operator. This think need to be fix in twig to. So as promises, here is my PR ! This is my first contrib to symfony so any advice is welcome ! 😁
