fix: correct mismatched option labels in SKILL.md (A-E menu vs sections) (#64)

Both the Chinese and English versions of SKILL.md had option labels
in the section headers that did not match the A–E menu presented to
users during Step 2.

Chinese bugs (before this fix):
- 方式 C：上传文件  → should be 方式 D (D=上传文件 in menu)
- 方式 B：飞书链接  → should be 方式 C (C=飞书链接 in menu) — duplicate B
- 方式 C：直接粘贴  → should be 方式 E (E=直接粘贴 in menu)

English bugs (before this fix):
- Option C: Upload Files  → should be Option D (D=Upload Files in menu)
- Option D: Feishu Link   → should be Option C (C=Feishu Link in menu)

Both menus are consistent with each other (A=Feishu auto, B=DingTalk,
C=Feishu link, D=Upload, E=Paste); it was only the section headers
that were out of sync.
