获取服务台工单详情和工单列表接口报错

https://open.feishu.cn/document/server-docs/helpdesk-v1/ticket-management/ticket/list 接口中定义的comments是一个对象，实际上接口返回的comments是一个列表，

将Ticket对象的commens改成列表即可修复：

代码文件路径为lark_oapi/api/helpdesk/v1/model/ticket.py

Start with lark_oapi/api/helpdesk/v1/model/ticket.py and compare the Ticket model with the Feishu Helpdesk ticket list documentation. Verify the actual comments response shape and check the Ticket constructor and builder annotations. Done means ticket-list and ticket-detail responses deserialize comments as a list of Comments objects without errors.
