`semicolon_if_nothing_returned` FP on `let-else` statements

[dswij]

Lint name:semicolon_if_nothing_returned

I tried this code:

#![feature(let_else)]
#![warn(clippy::semicolon_if_nothing_returned)]

fn fn_returning_option() -> Option<i32> {
    Some(1)
}

fn main() {
    let Some(_) = fn_returning_option() else { return; };
}

I expected to see this happen: nothing

Instead, this happened: semicolon_if_nothing_returned fires and suggests adding another colon after closing braces
