improve match arm with semi-colon help suggestion

[pacberries]

Code

use std::io;
use std::cmp::Ordering;
use rand::Rng;

fn main() {
    println!("Guess the number!");
    
    let secret_number = rand::thread_rng().gen_range(1..=100);
    println!("The secret number is: {secret_number}: ");

    println!("Please input your guess: ");

    let mut guess = String::new();

    io::stdin()
        .read_line(&mut guess)
        .expect("Failed to read line");
    
    let guess: u32 = guess.trim().parse().expect("Please type a number: ");
   
    println!("You guessed: {guess}");
    match guess.cmp(&secret_number) {
        Ordering::Less => println!("Too small!");
        Ordering::Greater => println!("Too big!"),
        Ordering::Equal => println!("You won!"),
    }
}

Current output

23 |         Ordering::Less => println!("Too small!");
   |                        -- ^^^^^^^^^^^^^^^^^^^^^^- help: use a comma to end a `match` arm expression: `,`

   |                        while parsing the `match` arm starting here

Desired output

Rationale and extra context

The reason why it should be changed is because the new error message makes it clearer you should replace ; with ,. I was following the book, and I encountered this error. I didn't understand how to solve it and asked on the community discord, then a user in the community server then helped me and I managed to fix the error.
