Remove authors from Cargo.toml

The Dioxus CLI generates a Cargo.toml with an `authors` field. However, [that field is deprecated](https://doc.rust-lang.org/cargo/reference/manifest.html#the-authors-field). If one uses a [toml linter](https://github.com/tombi-toml/tombi), this even results in a warning.

So this line should be removed in all templates.
