refactor: Move to Next.js 13

[anuragxxd]

Description

The project currently utilizes an older version of Next.js and follows an outdated directory structure with the pages residing in the old pages directory. This issue aims to migrate the project to the latest Next.js version (Next.js 13) and reorganize the project structure using the new apps directory pattern. This will enhance the project's maintainability, take advantage of new features, and align with best practices.

Addition Context

Next.js docs to migrate the project: https://nextjs.org/docs/pages/building-your-application/upgrading/app-router-migration

Thanks, @anubhav1206. I think unless @git-anurag-hub has already started on this, you are very welcome to give it a shot :)
