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

Start by locating the OpenAPI description for the GET / endpoint and compare its 2026-03-10 representation with the breaking-change documentation. Check how the /authorizations endpoint is represented and whether authorizations_url remains in the root response description. Done means the API description is consistent with the documented removal, with relevant validation passing if available.

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?
