Setting deprecated services properly

[NicoHaase]

API Platform version(s) affected: api-platform/core v2.5.6

Description
Symfony 5.1 has been released last week, and it's deprecation handling has changed a bit. According to symfony/symfony@f10413c, you need to use not only the deprecated tag in src/Bridge/Symfony/Bundle/Resources/config/api.xml, but also provide the package name and the version number in which the deprecation has been introduced.

How to reproduce
Start a new project based on Symfony 5.1 and API Platform

Possible Solution
Change each occurence of a deprecated tag to something like

<deprecated package="api-platform/core" version="2.5">The "%service_id%" service is deprecated since API Platform 2.5.</deprecated>
