Summary

Added a note requiring AWSControlTowerBaseline to be enabled for CfCT target OUs and updated URL formatting

Security assessment

The added note emphasizes enabling AWSControlTowerBaseline, a security-related configuration, but does not address a specific security vulnerability. The URL changes are formatting fixes. The documentation addition reinforces security best practices but does not indicate a new security feature or resolved security issue.
