feat(watch): show hint while watching `rustlings hint ...` command is not convenient when doing exercises with `rustlings watch`. This PR makes it possible for user to type `hint` while running `watch` and get hint text for exercise which is currently failing. e.g. ```rust ... --> exercises/variables/variables1.rs:13:36 | 13 | println!("x has the value {}", x); | ^ not found in this scope error: aborting due to 2 previous errors For more information about this error, try `rustc --explain E0425`. type 'hint' to get help: hint Hint: The declaration on line 12 is missing a keyword that is needed in Rust to create a new variable binding. ```
