Pure JS Next.js example

[matux]

Description of the change

This PR introduces a fully fledged Rollbar example in Next. This is what I had been using to test the SDK. I cleaned it up, and added a README (base written by Claude, then reviewed and modified).

This is a comprehensive Next.js example application that demonstrates Rollbar error monitoring integration. It provides a fully functional demo with interactive error testing capabilities and detailed setup documentation.

Key changes:

• Creates a complete Next.js application with Rollbar integration using @rollbar/react
• Implements various error testing scenarios (manual errors, uncaught errors, promise rejections, component errors)
• Includes comprehensive styling and responsive design for the demo interface

• [nitpick] The variable name 'nullObject' is misleading since it's intentionally set to null to trigger an error. Consider renaming it to 'nullValue' or 'intentionallyNull' to better reflect its purpose in the error testing context.

    const nullObject = null;
