PHP 8 support for Pimcore 10

[seybsen]

This handy set of recipes will not install with the current pimcore release (10.1.1 at this time) which requires PHP 8 now:

$ composer require w-vision/pimcore-deployer
[...]
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - deployer/deployer[v6.0.0, ..., v6.7.1] require php ~7.0 -> your php version (8.0.8) does not satisfy that requirement.
    - deployer/deployer[v6.7.2, ..., v6.8.0] require php ^7.2 -> your php version (8.0.8) does not satisfy that requirement.
    - w-vision/pimcore-deployer 1.4.0 requires deployer/deployer ^6.0 -> satisfiable by deployer/deployer[v6.0.0, ..., v6.8.0].
    - Root composer.json requires w-vision/pimcore-deployer ^1.4 -> satisfiable by w-vision/pimcore-deployer[1.4.0].

EDIT: ... nevermind, I realised that deployer itself has PHP 8 support only in their v7 beta at the moment
