Fix broken links (Devin)

[github-actions]

@devin-ai-integration Please fix the broken links detected by the scheduled link checker.

Instructions:

1. For each URL listed below, identify the source file containing the broken link
2. Try to find the correct replacement URL. Common fixes include:
   • Updating outdated commit SHAs to the latest commit
   • Fixing URL-encoded paths
   • Updating renamed file paths
3. IMPORTANT: If you cannot confidently find a correct replacement (e.g., the only signal is a 5xx/503 error, connection reset, or rate limiting), do NOT remove or modify the link. Instead, leave it unchanged and add a PR comment on the relevant line asking for manual validation.
4. Only update links/paths contained in this PR, not other links that follow a similar pattern
5. Run fern docs dev locally to verify your changes don't break anything
6. Push your fix to this PR branch
7. After CI posts a preview link, use it to verify that your changes actually fix the underlying issue, then post a comment to the PR mentioning that you have tested it using the preview link
8. When the PR is ready for review, request a review from @davidkonigsberg in GitHub and send a message in the Devin session that includes "<!here>" to alert everyone in the channel.
9. Delete the scaffold file (.github/broken-links/broken-links.md) as part of your fix

The [429] https://www.svgrepo.com/show/353804/google-analytics.svg link (used in fern/products/docs/pages/integrations/overview.mdx) was flagged due to rate limiting, not a genuine broken link. I've left it unchanged per the PR instructions. Manual validation may be warranted if it continues to fail.

Verified via the preview link at https://fern-preview-devin-fix-broken-links.docs.buildwithfern.com/learn that the site builds successfully. The zh translation pages return 404 on both production and preview (likely ISR/on-demand rendering), but the broken github-secret.png reference has been fully removed from the source — confirmed with grep -c "github-secret" fern/translations/zh/products/sdks/generators/python/publishing-to-pypi.mdx returning 0 matches.
