Built-in alias `cargo rm` need its spot in configuration doc

Problem

cargo rm, an alias to cargo remove, should be mentioned in chapter Configuration in The Cargo Book.

Notes

We may or may not want to mention the alias command in each manpage of all subcommands. Anyhow, that ought to be a separate issue. At this moment, the user can run cargo --list | grep 'alias:' to find all aliases.
