This limits the expressiveness of a lot of code. Enums are sometimes a good way to model object state, but they often can't be used.

Remove author requirement for `cargo_common_metadata`

This PR follows rust-lang/cargo#9282, I'm not fully informed about all of this, it would be great if somebody knowledgeable about this topic agrees.

changelog: Changed `cargo_common_metadata` to stop linting on the optional author field.
