[CI] Add path-filters and fix branches for check-docs (backport #519)

[mergify[bot]]

• Add path filters to all build jobs
• Since https://github.com/ros-controls/control.ros.org/pull/293 we need to specify rolling instead of master for the reusable workflow.
• I also added the correct versions for the other distros now.
