Bug report: Missing optional configuration parameter in event sources for Lambda

Question

[DestinationConfig](https://docs.aws.amazon.com/lambda/latest/dg/API_CreateEventSourceMapping.html#SSS-CreateEventSourceMapping-request-DestinationConfig) is a configuration object that specifies the destination of an event (Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Kafka only) after Lambda processes it.

[AWS Lambda now supports failed-event destinations for Kafka event source mappings](https://aws.amazon.com/about-aws/whats-new/2023/11/aws-lambda-failed-event-destinations-kafka-event-source-mappings/). But the [Lambda developer guide](https://docs.aws.amazon.com/lambda/latest/dg/with-msk.html#services-msk-parms) doesn't reflect this configuration parameter for MSK, self managed Apache Kafka, Kinesis or even DynamoDB streams. It can be added.

Answer

Also, the documentation can be made available as a part of [this repo](https://github.com/awsdocs/aws-lambda-developer-guide]) so that we can directly raise a PR.
