Proposed tutorial flow:

1. How to import turtlebot to some example scene. For example https://github.com/o3de/o3de-extras/tree/development/Templates/Ros2RoboticManipulationTemplate
2. Starting the simulation
3. Configuring rai_whoami_node node using documentations and screenshots from the simulation
4. Writing a simple RaiAgent.
5. Connecting to the agent using streamlit-based web interface
6. Asking questions about the robot, what are it's interfaces.
7. Asking what the robot can see - it can describe the manipulator that is on the table
8. Asking the robot to move around
9. Oops - developer forgot to add ros2 publish to topic tool to the agent - robot can't perform the mission
10. Adding the tool
11. Robot drives forward
