Add support for Symfony 8

[Jean-Beru]

Add support of Symfony 8 and fixes typehint errors like

Compile Error: Declaration of Symfony\Bundle\MonologBundle\MonologBundle::build(Symfony\Component\DependencyInjection\ContainerBuilder $container) must be compatible with Symfony\Component\HttpKernel\Bundle\Bundle::build(Symfony\Component\DependencyInjection\ContainerBuilder $container): void

This is a breaking change. We should think about releasing a new major.

Or use that trait trick you created :)

Sure. If so, we could also think about removing support of sf < 6.4.

Or use that trait trick you created :)

What trait trick? I'm curious 🙂

even the trait trick would be a BC break (but a conditional one, which is even worse to communicate)

However, given the time since the last major version, I think we could do one.

If so, we could also think about removing support of sf < 6.4.

this does not actually require a major version. We can do it in a minor version if we ensure we update the composer requirements properly (as composer will install compatible packages)

I would prefer to go with a new major here in the case of our bundle.
