docs(README.zh-CN): sync Product Hunt badge + install URL with English

[YOMXXX]

Summary

• After the Simplified Chinese README was added in feat: add Simplified Chinese README translation #1890, two follow-up tweaks to README.md (Update README.md #1895, Update README.md #1903) were never mirrored into README.zh-CN.md.
• Apply both upstream diffs verbatim to README.zh-CN.md so the Chinese edition matches the English source.
• README.ja-JP.md is already in sync with both changes — no edit needed there.
• Documentation-only — no code, tests, or behaviour change.

Problem

README.zh-CN.md is the user-facing landing page for Chinese-speaking visitors arriving via the language badge / Trendshift / Product Hunt referrals. Two upstream changes drifted away from it:

1. Product Hunt badge (Update README.md #1895, commit bd5c2ed3): the English README migrated the embed from badge-featured / featured.svg to badge-top-post-badge / top-post-badge.svg, and merged the two separate <p> blocks (one for Trendshift, one for Product Hunt) into a single centred row with   spacing. The Chinese README still shows the older featured badge in its own block, so visitors see a stale "OpenHuman is Featured" widget instead of the current "Top Post" widget — and the layout differs between editions.

2. Install URL (Update README.md #1903, commit df542e72): the English README dropped ?utm_source=github&utm_medium=readme from the URL inside the install code block's comment, so the URL shown to users matches what they would actually type. The Chinese README still carries the tracking parameters in the comment, which is both inconsistent and slightly confusing (the prose link above it kept the params; only the in-code comment was simplified).

README.ja-JP.md was added later (#2005) and already includes both fixes, so it does not need touching in this PR.

Solution

Apply the two upstream diffs to README.zh-CN.md:

• Replace the featured Product Hunt block with the top-post-badge markup and collapse the two <p> blocks into one, matching README.md line 7-16 byte-for-byte (apart from the surrounding Chinese prose).
• Drop ?utm_source=github&utm_medium=readme from the comment line inside the install code block (line 48), matching README.md line 49.

No other content is touched. This is the minimal diff that re-aligns the Chinese edition to the English source as of main.

Submission Checklist

• Tests added or updated — N/A: documentation-only change.
• Diff coverage ≥ 80% — N/A: only .md lines changed; diff-cover does not score Markdown.
• Coverage matrix updated — N/A: behaviour-only, no feature row added/removed/renamed.
• Affected feature IDs listed under ## Related — N/A: documentation correction.
• No new external network dependencies introduced — confirmed, only Markdown copy changes.
• Manual smoke checklist updated if release-cut surfaces are touched — N/A: README copy only.
• Linked issue closed via Closes #NNN — N/A: Suggestion: Add a Chinese version of README (README.zh-CN.md) #1886 (the original request to add a Chinese README) is already fulfilled by the merged feat: add Simplified Chinese README translation #1890; this PR is sync maintenance, not the original delivery. Happy to also close Suggestion: Add a Chinese version of README (README.zh-CN.md) #1886 in a separate comment if maintainers prefer.

Impact

• Runtime / platform: none.
• Performance / security / migration / compatibility: none.
• User-visible: Chinese-speaking visitors now see the current "Top Post" Product Hunt badge in the same layout as the English README, and the in-code install comment shows a clean URL.

Related

• Follows: Update README.md #1895, Update README.md #1903 (upstream changes that drifted from the Chinese edition).
• Original Chinese README: feat: add Simplified Chinese README translation #1890 (closes the spirit of Suggestion: Add a Chinese version of README (README.zh-CN.md) #1886).
• Follow-up PR(s)/TODOs: none — straightforward sync.

Poem

🐰 A badge doth shine more brightly now,
From featured to top-post we bow,
And links made clean without the noise,
Just simple paths that bring us joys!
Chinese docs dressed up fresh and neat,
A tiny change, a fresh repeat! ✨
