@clalancette jazzy release note update for ros2/rclpy#1216, can you take a look?

I think we should probably rearrange this page a bit. In particular, if you look at e.g. http://docs.ros.org/en/rolling/Releases/Release-Iron-Irwini.html , you'll see that there is a "New features in this ROS 2 release", as well as a "Changes since the Humble release" section. I think we should do the same here, and sort the existing items properly. Then we can add in the new item into "Changes since the Iron release" section.

@fujitatomoya does that make sense? Would you be willing to do that?

@clalancette sure thing, i will do that.
