ROS2-Tracing-Trace-and-Analyze fix for iron tutorial (backport #4675)

[mergify]

Matching iron branch of tracetools_analysis repository must be cloned.

If the default master branch is used instead, the follow-up rosdep install --from-paths src --ignore-src -y command will fail and return a seemingly unrelated error message:

test_ros2trace_analysis: Cannot locate rosdep definition for [test_tracetools]
