AWS efs documentation change
Summary
Updated terminology from 'Amazon EFS' to 'EFS' for consistency, removed redundant details about mount target creation for Regional/One Zone file systems, and added a reference link to mount target management documentation.
Security assessment
The changes are primarily editorial improvements and content restructuring. No security vulnerabilities, encryption, access controls, or authentication mechanisms are mentioned. The added link to 'Managing mount targets' relates to operational guidance rather than security features.
