Add Traditional Chinese (zh-TW) Jupyter notebooks for HF Course — Full Coverage (Chapters 1–11)

## Summary

The [Hugging Face NLP Course](https://huggingface.co/course/) has a Traditional Chinese (zh-TW) translation at [`huggingface/course`](https://github.com/huggingface/course) covering Chapters 0–9. The course MDX files embed "Open in Colab" and "Open in AWS Studio" badges that link to language-specific notebooks under `course//`.

**Goal:** Create zh-TW versions of all **60 notebooks** in the English canonical source, translating directly from English to Traditional Chinese across Chapters 1–11.

**Current state:**
- PR [#625](https://github.com/huggingface/notebooks/pull/625) (open) adds the first 2 zh-TW notebooks for Chapter 1.
- Chapters 1–6 zh-TW MDX files currently link to `course/zh-CN/` paths — these must also be updated in [`huggingface/course`](https://github.com/huggingface/course) to point to the new `course/zh-TW/` paths once notebooks are created.
- Chapters 7–9 zh-TW MDX files link to language-neutral `course/chapter*/` paths — these must similarly be updated.
- Chapters 10–11 zh-TW MDX translation does not yet exist.

This issue tracks all notebook work across three phases. All notebooks are translated from the English source (`course/en/`).

## Scope

| Phase | Chapters | Notebooks | Prerequisite |
|-------|----------|-----------|--------------|
| **1** (immediate) | 1–6 | 31 total (29 remaining) | Also update zh-TW MDX links in `huggingface/course` |
| **2** (future) | 7–9 | 23 | Also update zh-TW MDX links in `huggingface/course` |
| **3** (future) | 10–11 | 6 | zh-TW MDX translation first |
| **Total** | | **60** | |

## Phase 1 — Chapters 1–6 (immediate)

**Source:** copy the corresponding `course/en/` notebook → `course/zh-TW/`, translate all Markdown cells to Traditional Chinese.

**Companion PR needed:** after notebooks merge, open a PR in [`huggingface/course`](https://github.com/huggingface/course) to update the `notebooks={…}` URLs in the zh-TW MDX files from `zh-CN` paths to the new `zh-TW` paths.

zh-TW MDX files for Chapters 10–11 do not yet exist. Notebooks can only be added after the course MDX is translated in [`huggingface/course`](https://github.com/huggingface/course).

**Source:** copy the corresponding `course/en/` notebook → `course/zh-TW/`, translate all Markdown cells to Traditional Chinese.

## Background — how notebook links work in the course

Each interactive section embeds a `` component:

```mdx

```

Until the zh-TW notebooks exist, Phase 1 links 404 and Phase 2 links point to the wrong language.

---

## Translation guidelines

- **Markdown cells:** translate from English to Traditional Chinese.
- **Code cells and output cells:** no changes needed.
- **Terminology reference:** the zh-TW MDX source files in [`chapters/zh-TW/`](https://github.com/huggingface/course/tree/main/chapters/zh-TW) are the authoritative terminology reference.
- Key vocabulary (EN → Traditional Chinese):
- dataset → 資料集
- training → 訓練
- fine-tuning → 微調
- tokenizer → 標記器
- pipeline → 管道
- model → 模型
- embedding → 嵌入

## How to contribute

1. Pick one or more unchecked notebooks from **Phase 1 or 2**. Phase 3 is blocked until the zh-TW MDX for Chapters 10–11 is translated in [`huggingface/course`](https://github.com/huggingface/course) first.
2. Copy `course/en/` → `course/zh-TW/`.
3. Translate all Markdown cells from English to Traditional Chinese. Code and output cells are unchanged.
4. Open a PR targeting `main`. Batching multiple notebooks from the same chapter in one PR is encouraged (see PR #625 as a model).
5. After the notebook PR merges, open a follow-up PR in [`huggingface/course`](https://github.com/huggingface/course) to update the `notebooks={…}` URLs in the zh-TW MDX files to point to the new `course/zh-TW/` paths.
