Remove unused composer/package-versions-deprecated dependency

[stof]

That package is a composer plugin, which requires users to allow it in composer 2.2+, which will annoy them especially if the plugin is not needed.

The package is also being faded out in favor of the composer-runtime-api of Composer 2 (see https://github.com/symfony/symfony/issues/44726).

Thank you @stof

@jakzal I suggest doing a release for that change, to help projects upgrading to composer 2.2+
