Rolling Ridley has rolled onto Ubuntu Jammy

The migration to Ubuntu Jammy has been completed.

The first Rolling sync on Jammy is planned for Tuesday next week and much of the distribution is already available in the testing repository. ROS 2 core CI is now running on Ubuntu Jammy by default and the Rolling CI jobs will be moving over in the coming weeks.

Like all major endeavors in ROS, this one would not have been possible without the community of ROS maintainers and developers who have been asking questions, reporting issues, and suggesting fixes.
Thanks everyone!
