(chore): include Django REST framework in requirements and set up Ruff linter

[akshath3001]

Overview

We need the Django REST framework for Week-2 tasks(involving building REST APIs).
Code formatter and linter support was missing for python/backend. Ruff is the recommended Python formatter/linter.

Changes

• Add djangorestframework in backend dependencies
• Add charliermarsh.ruff to recommend VS Code extensions
• Configure the ruff formatter VS Code extensions

LGTM

I'll let other folks chime in before we merge

Please make changes in README that outline - how to use the lint tool, and that DRF is included in the starter project. Rest lgtm!

I have made the necessary changes in the README file. Although, despite using the command git config --global core.autocrlf true, some unnecessary spaces were included in README. The command was used against the following error warning: in the working copy of 'README.md', LF will be replaced by CRLF the next time Git touches it.
I request you to guide me on this.
Thanks

@akshath3001 - can you check your editor settings and try to get the CRLFs back to simple LFs - since this is an upstream merge, we want to make sure that all files are conventionally solid.
