feat: Migrate to Node.js 20

This commit updates the project to use Node.js version 20.

Changes include:
- Updated `engines.node` in `functions/package.json` to "20".
- Updated the Node.js version in the GitHub Actions CI workflow (`.github/workflows/test.yml`) to `20.x`.
- Added a placeholder `functions/config/config.json` to allow tests to pass, as the original configuration file is managed externally and not present in the repository.

The project builds successfully and all tests pass with Node.js 20.
