[brijeshb42]

@dav-is This will need to be fixed on docs-infra side. The docs build is failing on the auto-generated page.tsx that exports metadata.

[dav-is]

@brijeshb42 this is a Next.js issue, see vercel/next.js#91735

Changes:

• Bump next to 16.2.9 in docs/ and update lockfile resolutions accordingly.
• Bump @next/eslint-plugin-next to 16.2.9.
