Add support to Symfony v8.0 components

[llaville]

Feature Request

While I'm currently works on Symfony v8 support to my project https://github.com/llaville/box-manifest, I've noticed that only partial Symfony v8 components were installed.

Reason is given by searching for dependencies constraints
