docs(readme): add star history section to translated READMEs

[BlackHole1]

The root README embeds a star-growth chart that the daily star-history workflow refreshes in place, but none of the six translated READMEs under docs/ carried it. This adds the same <picture> block (light/dark SVG) with localized headings and alt text to the fr, ja, ko, ru, zh-CN, and zh-TW READMEs, pointing at ../assets/star-history/.

No workflow change is needed: the chart SVG filenames are stable and only their contents change on each refresh, so the translated copies stay current automatically. The <!-- star-history:start/end --> marker comments are deliberately omitted from the translations — the action's readme input only rewrites the root README.md, and if it were ever pointed at docs/ it would embed repo-root-relative paths that break from there; a static block avoids implying automation that doesn't exist.

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 10 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
