refactor #659 Upgrade required version of PHP to 8.0 (rimas-kudelis)

This PR was merged into the 1.11 branch.

Discussion
----------

~~This updates composer.json to match the requirements in Sylius/Sylius master: PHP `^8.0` and Symfony `^5.4`.~~

~~Also adds a the `extra/symfony/require` element with the value of `^5.4`. This will mean that whenever `composer require symfony/whatev` is issued, it will automatically require `^5.4` when possible, so you won't end up with a mix of packages from 5.4 and 6.x.~~

~~Also bumps `symfony/flex` requirement to `^2.0` (fixes #645).~~

This updates composer.json to require PHP ^8.0.

Also changes `dev-master` branch alias to `1.11-dev` (fixes #635). Although maybe that should already be changed to `1.12-dev` instead?
