Autogenerate API docs

Our format for API docs is great, but as they are manually created I can see how they can get out of sync quickly when we are making changes. We shouldn't do this before launch, but I wonder how we can autogenerate API docs, kind of like how we do wirth `make gen` on coder/coder

首先，审查当前 API 文档是如何手动创建的，并将该流程与 coder/coder 中的 `make gen` 进行比较。明确涉及哪些 API 源和生成的输出；当文档能够可靠地重新生成并与 API 变更保持一致时，这项工作就完成了。
