Support for twig-cs-fixer

[babaorum]

First of all, thank you for this awesome set of tool to use.

From my current understanding, most of the heavy work for having those tools inside phpqa is done in this repository.

I am interested in adding twig-cs-fixer to the list.
I saw that there are already several twig linter supported.
This package is now quoted in the official documentation of twig https://twig.symfony.com/doc/3.x/coding_standards.html

If it would be ok for you, I can try to open a pull request with this.

Thank you in advance.
