chore: update Node.js version in CI workflow

Change Node.js version from a specific patch version
22.22.1 to the more flexible 22.x in GitHub Actions
workflow. This ensures compatibility with the latest
npm versions, which require Node.js ^22.22.2 or higher
to function properly, preventing installation errors.
