Add Nezha credential redaction fix references

[cookesan]

Adds Nezha credential redaction fix references to GHSA-ww5p-j6cj-6mqq.

Audit refresh, July 8, 2026:

• Confirmed the live PR is open, ready for review, merge-clean, and the visible advisory check is green.
• Rechecked the merge-base diff: exactly one advisory JSON file changes (advisories/github-reviewed/2026/06/GHSA-ww5p-j6cj-6mqq/GHSA-ww5p-j6cj-6mqq.json), JSON parses, git diff --check passes, and the exact-head worktree is clean.
• Revalidated the added public references in the diff; all resolve through their source site or registry.

Review note: this expands the Nezha advisory with a credential redaction fix commit and fixed release reference, plus EOF newline normalization. Affected ranges, severity, and advisory metadata fields are unchanged. Commit 39d398066d8c644fe452f74704e34ada6c7ab61e resolves to the DDNS/notification credential redaction fix, and the v2.2.5 release URL returns 200. The advisory JSON validates against the OSV schema.
