Fatal error on "Disable stored payment details" API call

[anton-close]

Describe the bug
\Adyen\Service\Checkout\RecurringApi::deleteTokenForStoredPaymentDetails() gives fatal error "Adyen\Service::requestHttp(): Return value must be of type array, null returned".

The problem is that this method $this->requestHttp($endpoint, strtolower('DELETE'), null, $requestOptions); must return array, but in fact NULL is returned. Adyen API
curl -X DELETE 'https://checkout-test.adyen.com/v70/storedPaymentMethods/{RECURRING_DETAIL_REFERENCE}?merchantAccount={YOUR_MERCHANT_ACCOUNT}&shopperReference={YOUR_SHOPPER_REFERENCE}' --header 'X-API-Key: YOUR_API_KEY'
returns 204 with empty response, but Adyen Service always expects array.

To Reproduce
Steps to reproduce the behavior:

1. Adyen PHP SDK version is 15.3.0.
2. Just call \Adyen\Service\Checkout\RecurringApi::deleteTokenForStoredPaymentDetails() method with required arguments

Expected behavior
No fatal error should happen.
