[BFCL] some tiny fix in possible_answer

[zhangch-ss]

I found an error ["Invalid value for parameter 'name': 'John Doe'. Expected one of ['j', 'o', 'h', 'n', '', 'd', 'o', 'e']."], in BFCL_v3_live_multiple_score.json.
this is because "John Doe" is not a list.
{"id": "live_multiple_189-83-0", "ground_truth": [{"sendHttpRequest": {"method": ["POST"], "url": ["https://httpbin.org/post"], "headers": [{"Content-Type": ["application/json"]}], "data": [{"name": "John Doe", "email": "john.doe@example.com"}]}}]}
I made a list of all similar errors and fixed them
