* Add option to skip the AvatarURL input request
Using an empty string for the avatar cli flag e.g. `git-bug user create
-a ""` will still result in a prompt. As the avatar URL is an optional
option, it should be possible to skip asking for it entirely.
Otherwise automated user creation via a script must make use of pipe hacks.
