Sets native livestream extensions to Isaac Sim 4.1-4.0 defaults (#954)

# Description

Streaming does not work for `isaaclab --livestream 1` using streaming
client 103.1.1.

This change sets the streaming client extension versions to the defaults
in isaac-sim-4.1.0/apps/omni.isaac.sim.headless.native.kit

Fixes #949
