AWS medialive documentation change
Summary
Updated terminology from 'video aligned pipeline locking' to 'video aligned locking' and added clarification note about availability only when output locking mode is set to PIPELINE_LOCKING
Security assessment
This change is purely terminological and clarifies feature availability. There is no evidence of addressing security vulnerabilities or weaknesses. The change describes functional behavior of video alignment locking without any security implications.
