I'm a little unclear on the GZ bridge changes. Are all (or any?) of them necessary? They seem to be doing the same thing in most cases, except for TF and a couple others having the GZ topic with a forward slash. I don't think that's necessary however and may actually break multirobot namespacing

[stevedanomodolor]

There are not necessary, just took advantage to follow the same structure as https://github.com/ros-navigation/nav2_minimal_turtlebot_simulation/blob/main/nav2_minimal_tb4_sim/configs/tb4_bridge.yaml#L1.

About the multirobot namespace, I am not sure, Should I remove the slashes then?

[SteveMacenski]

Yeah revert these if they're not necessary. The TB3 supports namespacing right now but the TB4 doesnt

I would leave the changes to the other file becuase there are comments that might be usefull later, specifically the gps std_dev comment.
