`/authorizations_url` is still a thing in the `/` endpoint under `2026-03-10` contrary to the documentation

Bắt đầu bằng cách tìm mô tả OpenAPI cho endpoint GET / và so sánh biểu diễn ngày 2026-03-10 của nó với tài liệu về breaking change. Kiểm tra endpoint /authorizations được biểu diễn như thế nào và liệu authorizations_url vẫn còn trong mô tả root response hay không. Được xem là hoàn tất khi mô tả API nhất quán với việc loại bỏ đã được ghi nhận trong tài liệu và validation liên quan đạt, nếu có.

https://docs.github.com/en/rest/about-the-rest-api/breaking-changes?apiVersion=2026-03-10 says:

Remove authorizations_url from the API root (GET /) The OAuth Authorization API has been deprecated since 2020.

So, why do I still see it advertised?
