Misleading docs on P3 resurfaced `http::Response::new()`

Create the following Spin SDK P3 handler:

#[spin_sdk::http_wasip3::http_service]
async fn handle(_request: Request) -> impl IntoResponse {
    spin_sdk::http_wasip3::Response::new("done\n")
}

Rust gets mad at you:

Scroll down the docs to see what you are allowed to pass to new and:

It's confusing that the docs show an example of passing an &str but you're not actually allowed to. Unfortunately the Response type is a re-export so we don't control the docs.

Amusingly, you can return an &str directly...

#[spin_sdk::http_wasip3::http_service]
async fn handle(_request: Request) -> impl IntoResponse {
    "done\n"
}

...you just can't use one in a Response.

Start by reading the P3 handler example and the documentation for spin_sdk::http_wasip3::Response::new, then verify where the re-exported Response documentation is generated or maintained. Done means the documented argument matches what the example accepts, or the example no longer presents an invalid &str usage.
