Isaac Simulation Gate Node - Step parameter issues

@VickNV, sure. I already mentioned it here: Isaac Sim increase rate of /imu topic ROS2 - #8 by yhofmann.
There is also an image of my omnighraph with the gate (the gate was set to 4), as one can see in the plots of the camera and IMU topic both are published at the same (wrong) rate. IMU too low and camera too high.
