Fix build error of cabot_util for the latest ROS2

[tatsuya-ishihara]

When I pulled new docker image by (./manage-docker-image.sh -a pull -i all -o cmucal) and build workspace on new PC, I could not launch ROS2 with following error.

To fix this issue, I modified setup.cfg of cabot_util.
For the latest ROS2, "script_dir", "install_scripts" should be used instead of "script-dir", "install-scripts".

Old document for galactic
New document for humble

Please merge this change if there is no problem.

It seems the cause is colcon-core.
Galactic documentation uses dash so I think they should support it with galactic...
It is a relatively new issue. I think they will provide some fix.

Anyway, thank you for the fix.
I will test it with colcon-core 0.7.1 (latest 0.9.0), then merge it if it works without issue.

[daisukes]

It works with colcon-core 0.7.1
