Added gripper_controllers for osx_arm64

[WiktorJ]

I'm unsure why the package was excluded from osx, but I ran pixi run build and all seems to work.
In ros-humble there is a comment that it doesn't work for Mac and Windows (https://github.com/RoboStack/ros-humble/blob/e9557aa1a82f7434f6203c2f8d18aafb43a42884/vinca_osx_arm64.yaml#L39) but it seems this is no longer the case.

I cannot test with intel hardware so adding just for Apple silicon.

Just FYI, the issue upstream was that back in time the plugin was not compiling on osx and so there was some cmake logic to skip actual compilation on osx, but that was probably fixed long ago but the cmake logic remaining, and it was removed in ros-controls/ros2_controllers#1471 .

I think we can add it on all platforms, if there are problems we can always fix them later.

I added gripper_controllers on osx-64, and bumped moveit_servo and ros2_controllers build number, so they rebuild without the dependency on gripper_controllers removed.

@WiktorJ feel free to check my additional changes and let me know if they make sense to you.

@traversaro Looks great! Thank you for taking care of that.
