Add Symfony 8 Support

[Hanmac]

WIP so see if something is broken

Dependencies that blocks 8.0 Version:

• composer why-not vimeo/psalm "7.0.0-beta11"
  psalm/plugin-phpunit 0.19.5 requires vimeo/psalm (dev-master || ^6.10.0)

• composer why-not symfony/cache "v8.0.0-BETA1"
  doctrine/doctrine-bundle 3.0.0 requires symfony/cache (^6.4 || ^7.0)

• composer why-not symfony/doctrine-bridge "v8.0.0-BETA1"
  doctrine/doctrine-bundle 3.0.0 requires symfony/doctrine-bridge (^6.4.3 || ^7.0.3)

• composer why-not symfony/dependency-injection 8.0.0-BETA2
  matthiasnoback/symfony-dependency-injection-test 6.1.0 requires symfony/dependency-injection (^5.4 || ^6.2 || ^7.0)

Right now, it's just vimeo/psalm that is blocking:
psalm/plugin-phpunit > vimeo/psalm > symfony/console: ^6.0 || ^7.0

other projects removed psalm checks from their code

[loevgaard]

Yeah, just remove that and add phpstan :D

[loevgaard]

Set reportUnmatchedIgnoredErrors: false inside the phpstan config

[Hanmac]

Can we drop PHP 8.1 if it's only supported til "31 Dec 2025"?

[loevgaard]

Not a fan and I believe it shouldn't. Is there a good case for it?

[Hanmac]

Stupid phpunit
in < 11.0, "once" and "never" are static methods (PHP 8.1)
in >= 11.0, "once" and "never" are instance methods (PHP 8.2)

phpunit itself doesn't complain about when I try to call the statics as instance variables,
but phpstan does.

[Hanmac]

PHP 8.5 does pass too

[loevgaard]

Great work 🎉
