V2.4.0

Added ROS2 Jazzy support.
NOTE: The ros2ez command has now been disabled, since currently two ROS2 LTS versions are supported. ROS2 Humble can now been used with the ros2ezh command, following the typical rosez*/ros2ez* scheme.
WARNING: This versions breaks humble installations. In order to migrate, your best bet is to rename ros2ez-volume* volumes to their equivalent ros2ezh-volume*.
