Adds access token scope to CLI

[freethejazz]

This simply adds a clarifying detail, that the access token only needs the user:email scope for setting up depot with GitHub authentication.

@freethejazz Thanks for adding some clarity to the CLI for users, this should be good enough for now!

In the future I think we need something in our documentation instead and a link to it in our CLI. That way we can explain a bit more about why we need certain scopes and the list can expand if we add additional required or optional scopes

There already is a bit of documentation in the getting started guide, but that might need to be augmented/moved to more a more general doc page: https://www.habitat.sh/tutorials/getting-started-setup-environment/ (see the Note: at the bottom of the page)

@freethejazz I think you're right, we should call it out in a more general place. @davidwrede what do you think?

Agreed. I'll open an issue and assign to myself.
