The GH_DEBUG environment variable is a new gh-specific verbosity control.
For backwards-compatibility, DEBUG will still be respected if it has values
"1", "true", "yes", and "api", but any other values will be ignored.
Finally, support for "oauth" debug value has been dropped in favor of "api".
The "oauth" value only had limited, internal use.

Fixes non-interactive login flow and make sure "prompt" configuration is
respected by never prompting if it was explicitly disabled.
No longer asks to press Enter again after "Authentication complete"
message, since that didn't provide any value to the user.
This removes sensitivity to the BROWSER environment variable in tests
and makes it easier to verify the URL that the browser was invoked with
without having to stub sub-processes.
Since GitHub CLI now offers to authenticate your Git as well, the token
we request here will be used for git pushes. Since we do anticipate our
users making edits to their GitHub Actions workflow files, we want them
to be able to push their changes, and this scope allows that.
