shadow_unrelated does not register a variable being shadowed

[nemqe]

I accidentally shadowed a variable without knowing and the linter did not warn me about that. Not a huge deal but just wanted to report the issue.

Lint name:
shadow_unrelated

I tried this code:

let s = "&str";
println!("{}", s);

let s = String::from("String");
println!("{}", s);

let x = 1;
println!("{}", x);

let x = "2".parse::<i32>().unwrap();
println!("{}", x);

I expected to see this happen: Warning shown about variables s and x being shadowed when running cargo clippy -- -W clippy::shadow_reuse -W clippy::shadow_same -W clippy::shadow_unrelated.

Instead, this happened: No warning for variable s was shown.
