AWS lexv2 medium security documentation change
Summary
Updated documentation dates, added entry for AWS managed policy allowing tag and resource-based policy replication, and formatted existing entries with dates in titles.
Security assessment
The change adds documentation about updates to the AmazonLexReplicationPolicy managed policy, explicitly addressing permissions for tag and resource-based policy replication. This relates to security controls (IAM policies) and could impact access management for replicated resources. The policy update suggests enhanced security controls for global resiliency features.
