bloom release 3.3

[christian-rauch]

Can we get a new release for the 3.3 version? I think this now has to happen via the rolling release repo at https://github.com/ros2-gbp/apriltag-release. For ROS 1, I think we only need to support noetic. For ROS 2, the LTS versions foxy and humble should be sufficient. I am not sure how the release to rolling works. Could we also just release to rolling and it gets automatically released to all other stable distributions?

Given considerations to drop the vendored apriltag altogether due to it becoming available upstreamed via the distros (ros/rosdistro#35273), I'll ask first before making a release of 3.3

And yes, if we release to rolling before it gets copied over to iron it will automatically be in the future iron release.
