Paraunit 2.7.1: Symfony 8 support
This small new patch was triggered by a PR from a new contributor, Kocal, thank you! The fixes needed to make Paraunit compatible with Symfony 8 was a single line change (plus some more in the unit tests), which is impressive since now we support 5 different major versions, all across from 4.4 (which is EOL) up to 8.0!
