AWS sagemaker documentation change
Summary
Updated AL2 to AL2023 upgrade timeline dates and added clarification about phased upgrades for security/compatibility.
Security assessment
While the change mentions security as a reason for upgrades, it only adjusts existing migration timelines and adds no new security features or vulnerability documentation. The security reference is part of routine maintenance justification.
