docs(i18n): apply cp -r flatten fix to zh-CN, ko-KR, pt-BR, tr translations

Mirrors the previous commit's fix into the remaining translated docs
that carried the same `cp -r .../<lang>/* <target>/rules/` form:

- docs/zh-CN/README.md (3 install sections: Option A/B blockquote,
  manual install block, and "Just rules" subset block)
- docs/zh-CN/skills/configure-ecc/SKILL.md (1 install block; comments
  also updated to drop "flat copy into rules/")
- docs/ko-KR/README.md (Option A/B blockquote, manual install block,
  "Just rules" block)
- docs/pt-BR/README.md (Option A/B blockquote, manual install block)
- docs/tr/README.md (single "Just rules" line)

Same mechanical transformation as the previous commit:
`rules/<lang>/* <target>/rules/` -> `rules/<lang> <target>/rules/<lang>`.

Full test suite (node tests/run-all.js): 2382 passed, 0 failed.
markdownlint clean on all modified files.

Part of #1879.
