docs: Link to checkpoint consumption from operations (#201)

Add an info box linking to the AWS Lambda durable execution SDK
checkpoint consumption reference at the end of each operation page
(callback, child-context, invoke, map, parallel, step, wait, and
wait-for-condition). Also add the same reference link to the end of
the Checkpoints section in key concepts.
