AWS cli documentation change

File: cli/latest/reference/elasticache/describe-replication-groups.md

Summary

Updated encryption documentation: clarified AtRestEncryptionEnabled behavior, added StorageEncryptionType field, and introduced Durability/EffectiveDurability fields

Security assessment

The changes enhance documentation about at-rest encryption features but don't indicate any security vulnerability being fixed. The added StorageEncryptionType field helps users verify encryption status, improving security visibility without addressing a specific security issue.
