publish xUnit test result report failed in ros2 ci

[flynneva]

see it here for the grbl_ros ROS2 package.

looks like the build & test went fine but the publishing of the report failed, causing the ci to fail.

i noticed the most recent commit to this repo says something about junit....does that fix this issue?

For Focal and older distros this issue has been address by ros-infrastructure/ros_buildfarm#836 - see the latest build:

It seems like you repository hasn't been added to Rolling yet. For that I would expect that you package needs a patch similar to ros2/rclpy#587.
