[Validator] Fix parameters list in Choice::$multipleMessage option

Documentation says that `\Symfony\Component\Validator\Constraints\Choice::$multipleMessage` option can take parameters `{{ value }}` and `{{ label }}` in the message, but regarding `\Symfony\Component\Validator\Constraints\ChoiceValidator`, this is wrong. Just like for the other use-cass of `Choice` messaging options, it cannot take `{{ label }}` but `{{ choices }}` instead.
