[Bug]在QQ开放平台机器人下使用webhook的方式发送URL图片显示富媒体文件格式不支持

[wrnxr233]

What happened / 发生了什么

在QQ开放平台机器人下使用webhook的方式发送URL图片显示富媒体文件格式不支持，文字消息正常，视频发送未测试。
同样的环境下，用WS的方式的时候就没有问题，切换到WH就出现了这个问题。
（有个小细节：我的图片是请求的时候实时渲染的，API地址结尾不是图片格式而是.php）

Reproduce / 如何复现？

用webhook的方式发送url图片

AstrBot version, deployment method (e.g., Windows Docker Desktop deployment), provider used, and messaging platform used. / AstrBot 版本、部署方式（如 Windows Docker Desktop 部署）、使用的提供商、使用的消息平台适配器
