Goodbye ENV Files

Three months ago we stopped using ENV files as the default export option in the Doppler CLI, replacing them with JSON due to its stricter schema and strong native support in most languages. The switch has greatly reduced customer issues with parsing downloaded config files, and since the Doppler CLI creates a fallback of your secrets by default when running an application, we enabled encryption by default as well. This change has improved our customers' experience and provided a more secure way to manage secrets.
