Hello,

It's not possible to install the 4.6.* versions of this skeleton on PHP 8.3 due to the package lcobucci/clock not being up to date.

package version in composer.lock : https://github.com/ibexa/oss-skeleton/blob/v4.6.1/composer.lock#L4725
existing compatible version of the package : https://packagist.org/packages/lcobucci/clock#3.2.0
