allow-one-hash-in-raw-strings in clippy.toml not respected for needless_raw_string_hashes

[gwy15]

Summary

in https://doc.rust-lang.org/clippy/lint_configuration.html#allow-one-hash-in-raw-strings, there's a configuration which, as the name suggests, should allow using one hash for raw strings. But it is not currently respected for lint needless_raw_string_hashes.

Reproducer

I tried this code:

./clippy.toml:

allow-one-hash-in-raw-strings = true

./src/main.rs:

const S: &str = r#"
\d+
"#;

fn main() {
    println!("s = {S}");
}

I expected to see this happen: No lint.

Instead, this happened:

warning: unnecessary hashes around raw string literal
 --> src/main.rs:1:17
