ci: Add cs2pr handling for php-cs-fixer; avoid doing composer install (#814)

This PR uses the tools available from the [setup-php
](https://github.com/marketplace/actions/setup-php-action) action to
improve the feedback to better readable for humans using
[cs2pr](https://github.com/staabm/annotate-pull-request-from-checkstyle)
and avoids running `composer install` during the flow.
