不支持array形式的上报消息

[RockChinQ]

上报消息，示例如下：

{"post_type":"message","message_type":"private","time":1682421865,"self_id":2200000051,"sub_type":"friend","font":0,"sender":{"age":0,"nickname":"PokeBox","sex":"unknown","user_id":930000005},"message_id":1750478322,"user_id":930000005,"target_id":2200000051,"message":[{"type":"text","data":{"text":"hi"}}],"raw_message":"hi"}

和string格式的上报消息不同，需要对消息格式做处理。
下面是能正常使用的string的消息格式：

{"post_type":"message","message_type":"private","time":1682421386,"self_id":2200000051,"sub_type":"friend","message_id":1642095065,"user_id":930000005,"target_id":2200000051,"message":"!help","raw_message":"!help","font":0,"sender":{"age":0,"nickname":"PokeBox","sex":"unknown","user_id":930000005}}

报错导致的原因与go-cqhttp版本并无太大关系，当我使用的go-cqhttp版本是v1.0.0-rc5，目前几乎所有版本均支持string或array两种消息格式，设置方法为编辑config.yml文件，找到message下的post-format选项，并把值设置为array：

message:
  # 上报数据类型
  # 可选: string,array
  post-format: array

重启go-cqhttp和QChatGPT后，给机器人发送任意消息，即可复现上述bug。
