fix: add dotenv package for environment (#18)

* Added "dotenv" dependency to package.json

Since the project is using .env file for fetching the port, it had no "dotenv" dependency. This creates confusion when "process.env.PORT" doesn't work. I hope this is convenient for beginners 👍

* Update server.js

Added a line to import `dotenv` dependency to server.js.

* Update package-lock.json

I have added the dotenv dependency to package-lock.json file as requested. I hope it's good now
