LeptosOptions output_name is always leptos_config

Line 28 in 89f26f6

/// The name of the WASM and JS files generated by wasm-bindgen. Defaults to the crate name with underscores instead of dashes

The docs claim this refers to the crate name, but because crates are compiled independently, this name is always "leptos_config".
Should it be changed to CARGO_PKG_NAME instead?

MRE

#Cargo.toml

[package]
name = "repro"
version = "0.1.0"
edition = "2021"

[dependencies]
leptos = { version = "0.6.15" }

// src/main.rs

fn main() {
    use leptos::*;

    println!("Crate name is {}", env!("CARGO_CRATE_NAME"));

    let options = LeptosOptions::builder().build();
    let default_options = LeptosOptions::default();

    println!("Options output name is {}", options.output_name);
    println!("Default options output name is {}", default_options.output_name);
}

$ cargo run -q
Crate name is repro
Options output name is leptos_config
Default options output name is leptos_config

I believe if you ran a blame on this it was actually me that introduced this bug. Not that it really matters.

From my understanding of the docs here, the options to solve this problem aren't great unless you want to use a macro_rules! or build script.

Probably CARGO_PRIMARY_PACKAGE would be the next thing to try.

I could be wrong but the difference between between CARGO_PKG_NAME and CARGO_CRATE_NAME is that one exchanges - for _.
