Make init.author prompt like init.license

[ljharb]

https://github.com/npm/init-package-json/blob/master/default-input.js#L182-L194 doesn't prompt if the author is specified. However, https://github.com/npm/init-package-json/blob/master/default-input.js#L196-L200 prompts regardless, and just uses the init.license value as a default.

Would it be possible to prompt the user to confirm the init.author settings as well?

I support this. Although having different authors does seem like a rare occurrence, the option to change it should be there without having to unset init.author or manually edit the package.json file.

Not necessarily rare if your company has their own registry.
