AWS AmazonCloudWatch documentation change

Summary

Replaced inline JSON policy definitions with links to AWS Managed Policy Reference Guide and added 'cloudwatch:GenerateQueryResultsSummary' permission to managed policies

Security assessment

The changes remove verbose policy JSONs in favor of centralized references and add a new query summary permission. While permissions changes can impact security posture, there is no evidence this addresses a vulnerability. The update appears to document a new feature capability rather than fix a security issue.

-The **CloudWatchLogsFullAccess** policy grants full access to CloudWatch Logs. The policy includes the `cloudwatch:GenerateQuery` permission, so that users with this policy can generate a [CloudWatch Logs Insights](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html) query string from a natural language prompt. It includes permissions for Amazon OpenSearch Service and IAM to enable CloudWatch Logs integration with OpenSearch Service for some features. The full contents are as follows:
