Replace os.environ with dotenv for better environment variable management

[Chanchal-D]

Problem Statement

Currently, the repository uses os.environ[...] to access environment variables, which requires setting them manually in the system. This can lead to issues when running scripts across different environments.

Suggested Solution

Modify all scripts to use python-dotenv to load environment variables from a .env file. The new approach should follow this format:

import os
from dotenv import load_dotenv

load_dotenv()
API_KEY = os.getenv("API_KEY")
