Subject: [PATCH] refactor: remove deprecated SidebarTocNode and clean up
 sidebar TOC rendering

- Eliminate the deprecated SidebarTocNode from RenderContext and related functions.
- Update sidebar TOC rendering logic to exclusively use SidebarTocHeaders for improved clarity and maintainability.
- Remove fallback logic for legacy TOC rendering to streamline the codebase.
