Fix deprecation notifications since SF 5.1

[ricohumme]

symfony/dependency-injection states deprecated tags in configurations should have the package name and the version the deprecation started.
This PR will fix that issue

@X-Coder264 fyi these test failures are not due to my contribution.
Could this be merged as the impact is low code-wise, but highly on the deprecation logs in the application for users working with SF 5.1+
Thank you in advance!

@ricohumme Some builds fail due to some message changes which were recently made in league/oauth2-server package. But some builds fail due to this change as IIRC this change is not compatible with Symfony 4.4 and 5.0 which we still support on the master branch.
