_setup_managed_agents in MultiStepAgent defines a schema for managed_agents.
The schema contains additional_args.
additional_args is not always needed when managed_agents are called and some models don't set it when calling the agent.
When using managed agents I ran into them being called and giving the error
Argument additional_args is requireduntil the maximum number of steps is exhausted.
Making additional_args nullable in the schema fixes this.
