`Display` is not implemented for `StringAttribute`

[tguichaoua]

In the Attribute Passthrough chapter of the book, in the last code block we have

use sycamore::web::StringAttribute;

#[component(inline_props)]
fn Button(
    #[prop(attributes(html, button))]
    attributes: Attributes,
    // StringAttribute is a type alias for MaybeDyn containing a string.
    class: StringAttribute,
) -> View {
    // We still want the attribute to be reactive.
    let class = move || format!("{class} custom-button");
    view! {
        button(class=class, ..attributes)
    }
}

But StringAttribute is a type alias for MaybeDyn<Option<Cow<'static, str>>> which didn't implement Display.

One possible solution will be to turn StringAttribute into a new type around MaybeDyn<Option<Cow<'static, str>>> (with Deref and DerefMut) and implement Display for it.
