[Docs] README 链接错误

[CreeperIsASpy]

Please refer to the official documentation: Deploy AstrBot with Docker.

README 中此处的链接应指向 https://docs.astrbot.app/deploy/astrbot/docker.html#使用-docker-部署-astrbot，而不是 https://astrbot.app/deploy/astrbot/docker.html#使用-docker-部署-astrbot。
现在点击这个链接会去到官网首页，不对劲。

Hi @CreeperIsASpy! I'm Dosu and I’m helping the AstrBot team.

确认了，这个错误链接在 README.md 第 103 行，域名应从 astrbot.app 改为 docs.astrbot.app。

To reply, just mention @dosu.
