Title: Upload .env.example, Remove .env, and Update .gitignore for Smoother Development

Description:
To ensure smoother collaboration and deployment, we need to make the following changes:

1. Upload a .env.example file:
   This file should include all the necessary environment variables without any sensitive information (e.g., API keys, database credentials). It will serve as a reference for other developers to create their own .env files.

2. Remove the .env file from the repository:
   Sensitive information should not be committed to version control. We'll remove the existing .env file from the repository to ensure it isn't exposed.

3. Update .gitignore:
   Add the .env file to .gitignore to prevent it from being accidentally committed in the future.

Tasks:

1. Create a .env.example file with placeholder values.
2. Remove the .env file from the repository.
3. Update .gitignore to exclude .env.

You don't need to raise an issue just for this. I'm not going to add any level just for this.
