[BUGFIX] Require a PHP-CS-Fixer version that supports the PER standard (#83)

* [BUGFIX] Require a PHP-CS-Fixer version that support the PER standard

We recently switch from PSR-2 to PER as our base coding standard.

As this standard got introduced in PHP-CS-Fixer 3.11.0, we need that
have this version as the minimum required version.

Fixes #82

* Extend CI
