Upgrading issue from 2.4.2 to 2.4.6 issue

I’m looking to upgrade my store from 2.4.2 to 2.4.6, I see it’s require PHP version 8.2.
So I’ve upgraded my php version then I run composer require magento/composer-root-update-plugin ~2.0 --no-update but I got the following error :

The "laminas/laminas-dependency-plugin" plugin was skipped because it requires a Plugin API version (">=1.1.0 <2.3.0") that does not match your Composer installation ("2.6.0"). You may need to run composer update with the "--no-plugins" option.

Then I’ve trying with the suggested command composer update --no-plugins but I got the following error :

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