The GitHub IDE plugin for Zed use http instead of https on local server which start authflow

**Steps:**

1. When start the IDE Plugin it ask to authenticate with GitHub Copilot. When user click authenticate the following url is open in the browser. `http://127.0.0.1:33428/signin?nonce=`
2. Most modern browsers doesn't load http pages like Safari for example.

A workaround is to change the url from `http://127.0.0.1:33428/signin?nonce=` to `https://127.0.0.1:33428/signin?nonce=`. This allow the auth flow to redirect to Github App Permission page and authenticate.

3. But then again the problem encounters with the callback url which is `http://127.0.0.1:33428/callback?browser_session_id=`.

A workaround for this is again to change from `http` to `https` to complete the auth flow.

从 Zed IDE plugin 的本地身份验证流程开始，检查它如何打开 /signin URL，以及如何处理 127.0.0.1:33428 上的 /callback URL。将这两个 URL 与所描述的浏览器行为进行比较，并在无需手动将 http 更改为 https 的情况下身份验证能够正常工作时，认为该流程已完成。
