Allow php version 8.0 and higher

[tulik]

Currently,

        "odiseoteam/sylius-blog-plugin": "^1.3",

allows PHP 8.0 and higher, but installation is interrupted by the following error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - odiseoteam/blog-bundle[v1.1.0, ..., v1.1.6] require php ^7.1 -> your php version (8.0.9) does not satisfy that requirement.
    - odiseoteam/blog-bundle[v1.1.7, ..., v1.1.25] require php ^7.2 -> your php version (8.0.9) does not satisfy that requirement.
    - odiseoteam/sylius-blog-plugin v1.3.0 requires odiseoteam/blog-bundle ^1.1 -> satisfiable by odiseoteam/blog-bundle[v1.1.0, ..., v1.1.25].
    - Root composer.json requires odiseoteam/sylius-blog-plugin ^1.3 -> satisfiable by odiseoteam/sylius-blog-plugin[v1.3.0].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
