Code Review

This pull request updates Next.js to version 15.5.2. The changes in yarn.lock correctly reflect this update. I have added one comment regarding a related dependency, eslint-config-next, which should also be updated to maintain consistency and ensure correct linting rules are applied.

[gemini-code-assist]

While the next package is being updated to version 15.5.2, the eslint-config-next package in js-sdk-framework-tests/nextjs/package.json remains at version 14.2.13. It's important to keep the ESLint configuration aligned with the Next.js version to ensure correct linting rules are applied and avoid potential issues. Please consider updating eslint-config-next to match the new Next.js version, for example to ^15.5.2 or latest.

Updated eslint, too. Thanks Gemini Code Assist. You're the best.
