Update Cargo.toml in getting-started doc

[deepak]

I am learning rust and reading the book for the first time

in https://github.com/rust-lang/rust/blob/9094935b460975b6fac272ebf5985dfd71b90104/src/doc/book/getting-started.md#making-a-new-cargo-project-the-easy-way

the generated Cargo.toml has changed

slight difference is that it has a section called [dependencies]

should we specify the actual file ?

It should look like the generated Cargo.toml file. Want to open a PR to fix this?

[deepak]
