Fix `gh` check failing due to missing github organization

[bmonkman]

If someone chooses not to automatically check their created repositories into github we skip the follow-up question which asks for the github organization to use. This has the unintended side effect of causing the module checks for gh to fail since they attempt to use the github org in the API call. Maybe let's just reword this in internal/init/init.go to something like "What's the root of the github organization that will own these repositories?" and always ask it.
