Typing too strict for GetContactInfoResponseStatisticsUnsubscriptionsUserUnsubscriptionItem::$campaignId

[amlbcd]

Hello,

I tried using both the latest v4 tag and the v5 rc and they both have this bug.

To reproduce it, unsubscribe a contact using an unsubscribe form and then try to fetch this same contact details:

$contactInfo = $this->client->getContacts()->getContactInfo(
    $email,
    new GetContactInfoRequest([
        'identifierType' => GetContactInfoRequestIdentifierType::EmailId->value,
    ]),
);

You will get this error :

The property should be nullable.
