ci(rolling): allow ROS2 Rolling job to fail (upstream package missing)

ros-rolling-point-cloud-interfaces was dropped from the apt sync circa
2026-04-25; the last green Rolling run on main was 2026-04-20. The
package is still required by cloudini_ros (CompressedPointCloud2 message
type used by the publisher/subscriber plugins), and is present on
Humble/Jazzy/Kilted. Mark Rolling continue-on-error so PR checks don't
block on this upstream regression. Revert once the deb is restored or
we migrate off point_cloud_interfaces.
