Slight improvement for suggesting `is_ok()` and `is_err()` instead of `matches!()`

Description

This is a very minor enhancement suggestion. I just found very old code that looked like this:

pub fn test(r: Result<(), ()>) -> bool {
    match r {
        Ok(_) => true,
        _ => false,
    }
}

Instead of pointing the user to is_ok() clippy had the following output:

warning: match expression looks like `matches!` macro
 --> src/main.rs:4:5
  |
4 | /     match r {
5 | |         Ok(_) => true,
6 | |         _ => false,
7 | |     }
  | |_____^ help: try this: `matches!(r, Ok(_))`
  |

  = note: `#[warn(clippy::match_like_matches_macro)]` on by default

The relevant entry point is the match_like_matches_macro lint named in the report; start by locating its implementation and existing tests. Compare its diagnostic with the requested is_ok()/is_err() suggestion, then verify the intended cases in the lint test suite.
