[BUG]description for query paramters can not show in swagger ui
Hi, when I add a description for a schema used in query, it can not show in swagger ui but can show in Redoc
```py
@HELLO.route('/', methods=['GET'])
@api.validate(query=HelloForm)
def hello():
    """
    hello 注释
    :return:
    """
   return 'ok'

class HelloForm(BaseModel):
    """
    hello表单
    """
    user: str # 用户名称
    msg: str = Field(description='msg test', example='aa')
    index: int
    data: HelloGetListForm
    list: List[HelloListForm]
```
