Update ros_canopen release repository.

This release repository was forked into ros2-gbp for the Galactic migration in April 2021 and has not been released into the upstream repository since.

Since the [upcoming Rolling platform migration](#32036) will again branch the release repository into ros2-gbp I recommend that we update it pre-emptively to reduce churn in the bloom configuration branches.
