Depend on gz-ros2-control instead of gazebo-ros2-control

[abake48]

We currently don't support Gazebo classic and have focused on support Ignition Gazebo so we should no longer depend on gazebo_ros2_control and instead depend on gz_ros2_control.

This will benefit the user because gazebo-ros2-control and gz-ros2-control currently conflict with each other.

Rolling Binary Build Rolling + Main failed:

  ERROR: the following rosdeps failed to install

I think this is in a weird state right now due to the recent changes upstream https://github.com/ros/rosdistro/pull/37773

It looks like gz-ros2-control is available on main with Iron but not yet for Rolling. It is available on testing for rolling but our github jobs are setup to fail fast and not run the other matrix option.

This just means we need to wait until the next package sync for Rolling before merging.

@abake48, @moriarty, @smoya23 any chance this could be moved forward? gazebo-ros2-control has been phased out, so Rolling and Jazzy builds are failing because of the missing dependency.
