Update the documentation about Symfony integration and add Laravel integration

[carlos-granados]

The cookbook that describes the Symfony integration is very outdated, it uses the behat/symfony2-extension extension which was archived a long time ago and only supports up to Symfony 4. It should be updated to use the new friends-of-behat/symfony-extension extension.

But I wonder if it is worth to have a full cookbook about this integration or if it would be enough to point the users towards the documentation for this extension instead of repeating it all here

We should also point the users towards the documentation of the laracasts/behat-laravel-extension which provides similar capabilities for Laravel

I'd personally argue that if their docs are succinct that we point there rather than owning the cookbook, as we do not control when things change on their end?

That was my thinking as well
