Add 'SubmitEvent' to re-exported events from web_sys crate

[dyanechi]

Allows to use SubmitEvent type explicitly in closures to fix error when submitting form with on:submit.

Currently the following code:

let submit_fn = move |e: Event| {
    e.prevent_default();
};

view! {
    main(class="container") {
        form(on:submit=submit_fn) {
            button(type="submit") {
                "Submit"
            }
        }
    }
}

Will cause error:

the trait bound `{closure@src/app.rs:41:21: 41:36}: EventHandler<_, submit, _>` is not satisfied
the trait `EventHandler<_, submit, _>` is not implemented for closure `{closure@src/app.rs:41:21: 41:36}`rustc[...](...)
app.rs(45, 5): required by a bound introduced by this call
generic_node.rs(128, 12): required by a bound in `event`

Defining function with empty closure let submit_fn = move|_| {...} infers to impl Fn(SubmitEvent) but you can't call e.prevent_default() that prevents page refresh on submitting forms.

Unless there's better way to do it (like implementing, this simple re-export of SubmitEvent fixes the problem by allowing explicit type definition. This refactored function now compiles and works as expected:

let submit_fn = move |e: SubmitEvent| {
    e.prevent_default();
};

Seems like this was a typo from my part. I'm putting the blame on Copilot 😓
