[CI] Add jazzy and other minor updates (backport #1521)

[mergify]

• Add Jazzy workflows (I decided to create dedicated files, because it easier to maintain if we branch for jazzy)
• Add filters to run the ROS - workflows only if code has changed, and the doc workflow only if docs have changed. (branches+path filter have to match both to run the workflow)
• Check Docs - workflow now uses the correct branch of control.ros.org (not every page is available on every distro any more).
