PYTHON-5667: Update prompt.py

[Putu Gede Pradana Adnyana (pradanaadn)]

• Update the agent_toolkit prompt for the query checker to ensure it return pymongo syntax.

It keep return query in json:

================================= Tool Message =================================
Name: mongodb_query_checker

content='json\n{\n aggregate: "sales",\n pipeline: [\n { $unwind: "$items" },\n { $unwind: "$items.tags" },\n {\n $group: {\n _id: "$items.tags",\n totalSales: { $sum: { $multiply: ["$items.price", "$items.quantity"] } }\n }\n },\n { $sort: { totalSales: -1 } },\n { $limit: 5 }\n ]\n}\n\n\n### Explanation:\n1. Unwinding Tags: The tags field within items is likely an array, which requires an additional $unwind stage to flatten the array and properly group by individual tags.\n2. Identifiers and Operators Quoting: The identifiers and operators are quoted correctly in the original query, and there are no syntax errors related to quoting.\n3. JSON Validity: The query is valid JSON format as part of a MongoDB aggregation pipeline.\n\nThe main change is the addition of an extra $unwind stage for items.tags. This ensures the query groups by each individual tag rather than the array of tags.' additional_kwargs={'refusal': None} response_metadata={'token_usage': {'completion_tokens': 239, 'prompt_tokens': 178, 'total_tokens': 417, 'completion_tokens_details': {'accepted_prediction_tokens': 0, 'audio_tokens': 0, 'reasoning_tokens': 0, 'rejected_prediction_tokens': 0}, 'prompt_tokens_details': {'audio_tokens': 0, 'cached_tokens': 0}}, 'model_name': 'gpt-4o-2024-08-06', 'system_fingerprint': 'fp_a288987b44', 'id': 'chatcmpl-BqWxt1ajfavqmGTBS06BLsuDhCM1D', 'service_tier': 'default', 'finish_reason': 'stop', 'logprobs': None} id='run--75a8df8b-cf4e-4e79-aba0-dcea8b9c8e69-0' usage_metadata={'input_tokens': 178, 'output_tokens': 239, 'total_tokens': 417, 'input_token_details': {'audio': 0, 'cache_read': 0}, 'output_token_details': {'audio': 0, 'reasoning': 0}}
