Create BASE_IMAGE argument to fix rolling nightly builds

[CihatAltiparmak]

Rolling nightly builds uses osrf/ros-rolling-desktop-full docker image at where ROS2 is installed from apt. I have a case which I have encountered. In this case, geometry msgs was in testing phase, so I had to build geometry msgs locally.

Let me know if/when you want me to review

Btw updated my comment in order to show the mistake. I will test it in my other account. Bc it is not easy to test github workflow.

We have a version of geometry_msgs in Nav2's underlay that builds from source due to adding in a new message definition not yet in Rolling binaries. The nightly's for rolling are building correctly (https://github.com/ros-navigation/nav2_docker/actions/runs/12983823889/job/36205693741), so I wonder if your issue is that this needs to be rebased / pull in recent changes that fixed the docker builds to pull in Nav2's underlay during building. Else, if up to date, this may involve some kind of regression, but I don't see how that's possible (so I'm putting my money that you need to pull in the recent changes the past several weeks).
