### Context
Resource: [Next.Js: Migrating Existing Config](https://nextjs.org/docs/pages/building-your-application/configuring/eslint#migrating-existing-config)

We'll update ESLint's version to the latest and migrate its config file for Next.js 13+.

### Problem or idea
Based on the requirement above, update ESLint's version and config file in the project.

### Solution or next step
- Upgrade Eslint's version to the latest
- Update the`eslintrc.js` config file:
1. Install `eslint-config-next ` and add it to the `extends` property
2. Clean up any settings we no longer need.
- Run linting to fix any lining warnings/errors generated
