Fix broken /learn/ask-fern links in stainless-comparison.mdx

[github-actions]

Summary

The scheduled link checker detected 404s for https://buildwithfern.com/learn/ask-fern. The Ask Fern section was previously moved to /learn/docs/ai-features/ask-fern/, but 5 links in stainless-comparison.mdx still pointed to the old /learn/ask-fern/ path (which has no redirect for the bare path).

Changes:

• Updated 5 links in fern/products/docs/pages/resources/stainless-comparison.mdx:
  • [guidance documents](/learn/ask-fern/) → /learn/docs/ai-features/ask-fern/guidance
  • [custom knowledge sources](/learn/ask-fern/) → /learn/docs/ai-features/ask-fern/content-sources
  • [Ask Fern](/learn/ask-fern/) → /learn/docs/ai-features/ask-fern/overview
  • [Content gap identification](/learn/ask-fern/) → /learn/docs/ai-features/ask-fern/overview
• Deleted the scaffold file (.github/broken-links/broken-links.md)

Review & Testing Checklist for Human

• Verify the 3 destination URLs resolve correctly: /learn/docs/ai-features/ask-fern/overview, /learn/docs/ai-features/ask-fern/guidance, /learn/docs/ai-features/ask-fern/content-sources
• Confirm link text still makes sense for each destination (e.g., "guidance documents" → guidance page, "custom knowledge sources" → content-sources page)

Notes

• Other files (site-level-settings.mdx, dashboard/overview.mdx) also reference old /learn/ask-fern/getting-started/what-is-ask-fern paths, but those have working redirects (verified with curl returning 200) so they were not modified per the scaffold instructions.
