#### Why I did it
Upgrade xgs SAI version to 13.2.1.3 to include the following fix:
- [CS00012421016/CS00012421247]: bypass returning error log and error code for accessing trim disabled queue. Sonic currently doesnot have means to avoid accessing invalid trim queues and customer wants to return zero as value of counter. Added the bypass logic under a feat logic.
