Step 2: Go through ROS2 tutorials: Beginner: CLI tools

[jlunder00]

Follow the python version only of each of the tutorials if there are two versions (and swap to the python code example if it is not defaulted to that). If there are options for different operating systems at the top, choose linux, as you will be doing all of this in the docker container, which is linux.
