sync(zh): 同步 HuggingFace dataset canonical 路径修复（上游 #180）

HuggingFace 改了 dataset 命名规范，旧短 ID 弃用。上游把 09-data-management
的 dataset 路径更新为新 canonical 路径，1:1 同步：
- code/data_utils.py：rotten_tomatoes → cornell-movie-review-data/rotten_tomatoes
- outputs/prompt-data-helper.md：9 个 dataset 路径表格更新（纯英文 skill 文档，
  无中文翻译，整体对齐上游）

注：本批上游其余改动（4 课 docs 的交互式 figure 块、figures.js 图表引擎、
SEO 基建、About 页）因绑定站点功能或需中文适配，拆分到后续 PR 单独处理。

 When recommending, prefer smaller datasets for learning and prototyping. Suggest larger datasets only when the user is ready to train at scale.
