AWS cognito documentation change

Updated Lambda trigger retry behavior description from 'Amazon Cognito retries the call' to 'Amazon Cognito may retry the call' and clarified timeout conditions
Security assessment
This change clarifies retry behavior but doesn't address any security vulnerability or weakness. It's a documentation refinement about service behavior patterns.
