Question mark operator incomplete (?)

Looking at the questionmark operator page: https://doc.rust-lang.org/rust-by-example/std/result/question_mark.html

It seems that the introduction fail to mention that the operator could be used in a function that returns an Option too

Example using the Regex module:

fn parse_stuff(input: &str) -> Option<(&str, &str)> {
    let re = Regex::new(r"^(\d+)-(\d+)").unwrap();
    let caps = re.captures(&input)?;

    Some((caps.get(1)?.as_str(), caps.get(2)?.as_str()))
}

#[test]
fn test_parse() {
    assert_eq!(parse_stuff("1-33"), Some(("1", "33")));
    assert_eq!(parse_stuff("moo"), None);
}

(Since I'm a beginner I'm not comfortable proposing a PR, and maybe I'm wrong alltogether)

Start with the Rust by Example question-mark operator page linked in the issue and compare its introduction with the provided Regex example. Update the explanation to cover use in a function returning Option, using the example to verify the wording and behavior. Done means the page clearly explains both Result and Option use cases.
