Adds Documentation for Minimum Nodes

[marcoag]

I wouldn't say this subsection fits into the ROS 2 section as that one is specific for ROS 2 only documentation and what we are trying to add is on the RMF side of things. In fact there is already a section that talks about RMF simulation launch files that might be worth taking a look at and maybe merging some of the stuff here: https://github.com/thedevmanek/ros2multirobotbook/blob/nodes-docs/src/simulation.md#launch-files

We could add this info in the Simulation section. Maybe merge some of the launch stuff and then add a subsection for the explanation of the nodes? I would also like some more explanation on the nodes side like where's the code (links), how do they operate, who do they communicate with, configuration, messages... maybe it would be good to add some graph showing the nodes interaction (maybe generate one with rviz?) and how do they communicate, also the web side of things that communicates through websockets, how does it does that? are there any db involved?

It seems like the images have a circle in the bottom-left, is it relevant? if so can we add an explanation? if not, can the images be edited and remove this?

It was just there, there is no meaning to it. I have removed it in 89fd78f
