These changes are partially used in #219 and can potentially affect the behavior of Gazebo11 on Noetic. I think that we can merge both in this PR bumping Gazebo11.

Currently blocked at ros-infrastructure/ros_buildfarm#1080

The rollout process for this change will be different than usual. Instead of using the aptly scripts to apply this change on the bootstrap repository, we should specify it directly on build.ros.org in order to run it with the main repository import excluded.

Updating these packages in the normal bootstrap repository would cause any other import_upstream job to break the seal and put these packages in main.

Once the noetic sync as put these packages in main, it's probably worth going back and putting these in the bootstrap repository for all other build farms down stream of it.
