dash-seperated 'script-dir' will not be supported in future versions

Hello! I am just writing to report that I get the following warning when trying to build in ros2 humble on ubuntu jammy.

I am not sure when this deprecation will happen, but I just wanted to share in case someone has a version of setuptools where this does break

actually I am not sure if it runs out of the box on humble in general, so this might be ok to close
