Remove direct dependency on composer/package-versions-deprecated

This dependency in the doctrine-bridge was added to enforce the
replacement of the ocramius/package-versions package used by the ORM, to
keep support for PHP versions we needed. But as of 2.7.4, the ORM
switched its dependency, so this is not necessary anymore.
