Update all packages to latest possible versions to enable full php8 support.

[nfebe]

Description

Currently dependencies cannot resolve non-conflicting installable versions on php8.0. Failing build commands are marked with continue-on-error: ${{matrix.php-versions == '8.0' }} # [temp-php8] to ignore php8.0 errors in the .github/workflows/ci.yml. It's the required to also ignore build errors on php8.0 for phpList/rest-api which depends on phpList/core.

Once we are fully able to support php8.0 on core, build error for php8.0 ignored in phpList/rest-api may no longer be ignored.
