Uses python-coverage (Python 2) on Noetic

[StefanFabian]

Thank you for this ROS wrapper, I have used it for quite some time now on kinetic and melodic.
Unfortunately, it doesn't work on my Travis CI for noetic anymore for the following reason:
While the package correctly depends on python3-coverage for $ROS_PYTHON_VERSION==3, the command used is still python-coverage regardless of the ROS python version.
This obviously causes the process to fail on noetic as python-coverage is not installed (but python3-coverage is).

Could you please make a new noetic release so my noetic CI pipeline will work again? :)

Release was cut two weeks ago - I'm not sure when it will get sync'd to public - ros/rosdistro#27191
