[Documentation] Add Environment Variables Setup Guide

[Thisisaindia]

Problem

The README provides installation and setup instructions, but it does not clearly explain how to configure the required environment variables for the project.

New contributors may face difficulties setting up services such as Alchemy, Pinata, and backend configurations because the required variables and their purposes are not documented.

Proposed Solution

Add a dedicated Environment Variables Setup Guide section to the README that includes:

• List of required environment variables
• Description of each variable and its purpose
• Example .env file template
• Instructions for configuring Alchemy API keys
• Instructions for configuring Pinata API credentials
• Backend configuration examples

Benefits

• Makes project setup easier for new contributors
• Reduces configuration-related issues
• Improves onboarding experience
• Helps contributors start development faster
