Description of contribution in a few bullet points

The package never uses it, so don't declare it.

I noticed this because I noticed that recent builds of Navigation2 on Jazzy don't work on RHEL anymore, i.e. https://build.ros2.org/job/Jsrc_el9__navigation2__rhel_9__source/ is disabled. The reason for that is that python3-transforms3d is not packaged on RHEL-9. However, it turns out that this package doesn't actually use transforms3d, so the easiest thing to do here is to remove the dependency.

Note that if accepted, this should also be backported to the jazzy branch, and a new bloom-release should be done on the buildfarm for Jazzy.
