[TASK] Narrow down the Symfony development dependencies (#4034)

The Symfony development dependencies do not need to be in sync
with the TYPO3 Core Symfony dependencies as they are not installed
in projects that have this package as a dependency. Instead, it
suffices that the set of development dependencies is installable
(and works) with the PHP versions we support.
