Update axios version and add dotenv for environment vars

Upgraded axios to version 1.7.9 and integrated dotenv to manage environment variables. This change supports better configuration management by using .env files, as reflected in the new scripts and .gitignore entries. Additionally, minor code formatting improvements were made in `external-api.js`.
