[Task]: Follow up to `Replace Request::get with explicit input sources`

[mcop1]

Part of https://github.com/pimcore/data-hub/issues/679 , see https://github.com/pimcore/data-hub/pull/874

Despite being typed with mixed, Arraycan´t be passed as default value for request->get, needs to be a scalar value. The type gets checked in the function itself using is_sclar and therefore the type mismatch doesnt get detected by phpstan.
