text: Title: [DOC] Bring the Jupyter workaround tips elsewhere in the documentation
  Body: Hey Pydantic, thank you for this project.
  
  **Reference**
  #144 raises the issue of being unable to run the example in the doc, later fixed by #214
  
  **Doc improvement request**
  #214 put the work around notice only in the "Agent" section, which makes it barely visible in the documentation as a whole. For instance, I ran into this issue while testing function tools, in the corresponding section.
  
  Does it make sense to add this workaround notice to the main tutorial pages? I guess many new users will run into this, and some might not take the time to check your GitHub issue tracker.
  
  Thanks
