chore(kinesisfirehose-alpha): replacedestinations property with destination and change type from array to single IDestination

[paulhcsun]

Reason for this change

Setting a destination for your Delivery Stream was previously done by passing in an array of Destinations but with a restriction that there there could only be one Destination in that array. This property type does not make sense for the current user experience (have an array but can only specify one destination) and also does not align with the behaviour in the AWS Console which only allows you to select a single destination.

If Kinesis Firehose ever supports multiple destinations in the future then we can add a new property to support that which will not be a breaking change.

Description of changes

BREAKING CHANGE: replaced destinations property with destination (singular) and changed the type from array of Destinations to a single Destination. Old behaviour would only allow an array with a single Destination to be passed in anyway.

Description of how you validated changes

unit tests + no integ snapshot changes.
