clippy does not fire warning for ok_or usage

[aliciawyy]

Summary

When running the provided code in the Rust Playground, the expectation was for Clippy to produce a warning related to the usage of ok_or in accordance with the or_fun_call lint. However, Clippy did not generate any warning, contrary to the expected behavior.

Reproducer

I tried this code:

fn foo() -> String {
    println!("Called foo");
    "foo".to_string()
}

fn bar(x: bool) -> Option<i32> {
    if x {
        Some(1)
    } else {
        None
    }
}

fn main() {
  let v = bar(true).ok_or(foo());
  println!("v {:?}", v)
}

Playground demo: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=1cc70f21798932cb2cae892524e8cb20

I expected to see this happen:
I expect clippy to fire a warning for the ok_or usage as per or_fun_call.

Instead, this happened:
Clippy doesn't fire any warning

The lint is in the nursery category since #9829, so it is allow-by-default and needs to be opted into.

If you put #![warn(clippy::or_fun_call)] at the crate root, then you'll see the warning that you are expecting.

I see. Thank you!
