Describe the bug

When non-interactive mode, the auth and refresh flows still require interaction. Specifically they require pressing enter to interact with the browser, as well as to finish the flow.

gh --version: 1.12.1

Steps to reproduce the behavior

1. gh config set prompt disabled
2. gh auth login -w
3. See "- Press Enter to open github.com in your browser... "

Expected vs actual behavior

Instead it should give the URL to open as immediate output and block on validation.
