Note

Low Risk
Low risk: this only removes a client-side sort so anchor output order matches the API response; no API calls, parsing, or error handling behavior changes.

Overview
Updates prismic docs list <path> to stop alphabetically sorting entry.anchors by slug, so anchors are printed in the same order returned by the docs API (i.e., document order).
