MimicJointPlugin does not work for revolute joints

[zolanElleyoneD]

Hello,

I'm running Ubuntu 22.04 with ROS2 humble and gazebo classic. I tried to make the plugin work with revolute type joints (for context I'm making a car using the bicycle model inspired by this example: https://control.ros.org/humble/doc/ros2_control_demos/example_11/doc/userdoc.html and revolute joints are used for steering). The center joint turns, but the other two mimic joints don't. However, it's not that serious, I've put everything in continuous and, with some limitations on the angles, it works without a hitch. I just wanted to bring this error to your attention, I don't know if it's a feature that hasn't been added yet or just an error from the porting to ROS2. In any case, thank you for your work, which has been a great help in my project!

I didn't really understand what the issue is from the description, but if you could provide a working setup that I can try, I would be more than happy to investigate. As I mention in the readme, the ROS 2 version is untested, so this would benefit us both.
