chore: update GitHub workflows and package.json for Node.js 18

This commit upgrades the GitHub Actions workflows to use actions/checkout@v4 and actions/setup-node@v4, while also updating the Node.js version from 16 to 18 in both workflows and the package.json file. This ensures compatibility with the latest features and improvements in Node.js.
