fix: add more types to the type_map from python -> json schema

[cpacker]

Without this, the following tool can't get added (list doesn't work, neither does List[str]):

def analyze_campaign(campaign_name: str, metrics: list, time_range: str) -> str:
    """
    Evaluate campaign performance metrics.

    Args:
        campaign_name (str): Name of the campaign.
        metrics (list): List of performance metrics to evaluate.
        time_range (str): Time range for analysis (e.g., 'last_week').

    Returns:
        str: Campaign performance summary.
    """
    import random
    performance_data = {
        "meeting_requests": random.randint(5, 20),
        "meetings_booked": random.randint(10, 30),
        "pipeline_generated": f"${random.randint(100000, 500000):,}",
        "closed_won": f"${random.randint(50000, 300000):,}"
    }
    performance_summary = ", ".join([f"{metric}: {performance_data.get(metric, 'N/A')}" for metric in metrics])
    return f"Campaign: {campaign_name} | {performance_summary} in {time_range}."

@mattzh72 maybe it makes sense to kill this?
Optional[str]: "string",

because of the code above? if is_optional(py_type):

[mattzh72]

Hm yeah agreed - seems like above catches all the Optionals and unwraps them.
