Update rosdistro entries source/docs for released distributions from 'ros2' for rolling

[ahcorde]

We are planning to break ABI on message_filter I created this PR https://github.com/ros-perception/perception_pcl/pull/457 to fix the build job but I can see an issue in rosdistro.

There are branches for humble, iron and rolling (ros2 branch) but all rosdistro distributions are pointing to the ros2 branch

• rolling https://github.com/ros-perception/perception_pcl/commits/humble/
• jazzy https://github.com/ros/rosdistro/blob/master/jazzy/distribution.yaml#L4417-L4421
• iron https://github.com/ros/rosdistro/blob/master/iron/distribution.yaml#L4381-L4385
• humble https://github.com/ros/rosdistro/blob/master/humble/distribution.yaml#L5637-L5641

But I also check that there are some activity at least on the humble branch.

I would love to hear from the maintainers what to do here.

• override humble, iron and jazzy with the actual ros2 branch? and update rosdistro ? but this might destroy some work done for these old distros
• create a new branch for humble iron and jazzy based on ros2 and then continue working on ros2
• any other ideas ?
