AWS storagegateway documentation change
Summary
Added identical Pre-migration Checklist section as in tgw documentation, covering gateway images, hardware configuration, disk sizing, software updates, and network connectivity
Security assessment
Same as tgw file change: emphasizes migration procedures without addressing specific security issues or introducing security features. Software update recommendation is general maintenance.
