Describe the bug:
In the step_2_anthropic of "Agent Team" tutorial, the model name is given as gpt-4o whereas it uses Claude-Sonnet as the model for the exercise. My assumption is that the description and Instruction of root_agent must mention "Claude-Sonnet" instead of "gpt-4o".
Steps to reproduce
Go to "adk-docs/examples/python/tutorial/agent_team/adk-tutorial/", for tutorial on 'Agent Team'.
It has multiple steps. In agent.py of 'step_2_anthropic' folder, the model name is given as gpt-4o in the description and Instructions of Agent(), but it should be Claude-Sonnet instead.
