Add logging to AmazonShipping providers and cleanup

Introduce logging capabilities in `AmazonShippingRateProvider` and `AmazonShippingShipmentProvider` for improved error handling. Log detailed error messages from the Amazon Shipping API. Remove redundant `services.AddLogging()` calls in `AddRestApiAmazonRateProvider` and `AddRestApiAmazonShipmentProvider`.
