[TASK] Add return type declaration to FileDumpController::dumpAction

For historical reasons FileDumpController::dumpAction was allowed to
return null. It didn't specify a nullable return type declaration because
it was not yed decided whether v9 will require php 7.2 or not.
With https://review.typo3.org/55585 FileDumpController was adapted to
return a PSR-7 Response but missed to update the function signature.
The nullable annotation is therefore removed now and the explicit
return type declaration is added.
