Title: update default regex for parameters

I didn't find the commit or the point in the code but the exception says

```
An exception has been thrown during the rendering of a template ("Parameter "slug" for route "de__RG__frontend_show" must match "[^/\-]++" ("Fuss-ball" given) to generate a corresponding URL.") in ... show.html.twig at line 24.
