Update npm packages in package.json

[sweep-ai]

This PR introduces a new utility script that checks the version of each npm package listed in the package.json file, compares it with the latest version in the npm repository, and updates the package.json file if necessary.

The script is run with the command npm run update-packages. It uses the fs module to read the package.json file, the axios module to make requests to the npm API, and the child_process module to run the npm install command.

This will help ensure that the project is always using the latest versions of its dependencies, which can include important bug fixes and performance improvements.

Please review and let me know if any changes are required.

Fixes #24.

No changes required. The updates made to the package.json and the addition of the utils/packageUpdater.js file are well implemented. Good job!
