Add fix references to GHSA-35p6-xmwp-9g52 (undici)

[EchoTydes]

This advisory was missing links to the fix, so I've added them as references.

• Fix commit: nodejs/undici@6ea54ef
• Patched releases (each matches the advisory's patched version for its branch):
  • https://github.com/nodejs/undici/releases/tag/v8.5.0
  • https://github.com/nodejs/undici/releases/tag/v7.28.0
  • https://github.com/nodejs/undici/releases/tag/v6.27.0

The fix commit references this advisory, and each release's notes name GHSA-35p6-xmwp-9g52 and CVE-2026-6733. Additive change to the references only; no other fields are modified.
