Missing nav2_namespaced_view.rviz referenced in launch files

[k12onoss]

Both the cloned_multi_tb3_simulation_launch.py and unique_multi_tb3_simulation_launch.py reference a nav2_namespaced_view.rviz as a default rviz config file, but it doesn't exist anymore. Is there a reason for it's removal?

This is a good point! It looks like it was removed in an incorrect merge conflict resolution when readding in the multirobot launch files. I've readded it #4625 and will backport to Jazzy immediately.

It seems I didn't run into this in my testing since that config was still cached in my local workspace's install space.

Thanks for the report!
