Add skip pattern for audit PDFs returning 429 errors

[Copilot]

The link checker was failing on GitHub-hosted audit PDFs due to rate limiting (429 Too Many Requests).

Changes

• Added github.com/celestiaorg/celestia-app/blob/main/docs/audit/ to skip patterns in scripts/check-links.mjs
• Covers three audit PDFs in /app/learn/audits/page.mdx: informal-systems-v2.pdf, informal-systems-authored-blobs.pdf, and informal-systems-recovery.pdf

Pattern follows existing approach for rate-limited GitHub blob URLs.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
