Describe the bug

The gh binary does not appear to respect the GITHUB_TOKEN environment variable, where that token stores a "personal access token"

Steps to reproduce the behavior

Type

/ # GITHUB_TOKEN=MY_TOKEN_WAS_HERE gh auth status
github.com
  ✓ Logged in to github.com as kljensen (GITHUB_TOKEN)
  ✓ Git operations for github.com configured to use https protocol.
  ✓ Token: *******************

This shows me that I am good-to-go, I believe. But, then, when I try to clone a repo, I get the following prompt for a username:

/ # GITHUB_TOKEN=MY_TOKEN_WAS_HERE gh repo clone 'kljensen/dotfiles'
Cloning into 'dotfiles'...
Username for 'https://github.com':

The repo "kljensen/dotfiles" is private.

Expected vs actual behavior

I expected to be able to clone the repo because I had a valid GITHUB_TOKEN environment variable. Instead, I was prompted to authenticate.
