ROS2 Jazzy plugins fails with rosdep

Current evaluation

ROS2 Jazzy builds failed because rosdep's pkg_resources DeprecationWarning on stderr tripped the ROS plugin's output parsing. Hotfix PR #5609 was retargeted to #5615, merged as 721d86958, and shipped in Snapcraft 8.10.2.

Resolution: closed resolved

Reason: Merged PR #5615 (commit 721d86958) made the ROS plugin separate rosdep stderr from parsed stdout; maintainer @mr-cal confirmed the fix ships in Snapcraft 8.10.2 and the reporter verified the local build works. Root cause of the noise was also addressed upstream in rosdep 0.25.1 (ros-infrastructure/rosdep#984).
