Could the CLI have an interactive prompt for creds?

## Description

Ok this a 2 part question/request.

1. I'm curious as to why the `env.local` file was removed. I was having issues with my username/PAT and I found myself having to echo values over and over and this felt a little cumbersome as opposed to just looking at a single file.

2. For the folks who actually use the CLI it could be nice to have the CLI itself interactively prompt for the creds. I know there are several different commands that are run and this could add some complexity. Just a thought! It would create a really nice user experience.
