feature #111 Add Symfony 6 support (Kleinkind)

This PR was squashed before being merged into the 0.1-dev branch.

Discussion
----------

Add Symfony 6 support

- allowed symfony 6 in version constraints
- removed legacy-folder from phpunit config
- updated php-cs-fixer
- added ci-config for php 8.1 and symfony 6.0.*

⚠️ this also drops support for php 7.1 (php-cs-fixer 3.4 requires php ^7.2.5 || ^8.0)
