create_local_resource does not refetch when source signal changes on experimental-islands

[Houski]

Describe the bug
A create_local_resource inside an island does not re-run the fetcher when the source signal changes, in Leptos 6.0 beta versions (so far).

It was previously working on Leptos 5.5 (3f34d9b)

In this reproduction, you can see that the signal when routed through the LocalResourceTest ServerFn, does not re-run and match the signal itself. It remains blank, as it only appears to run the fetcher on initial load.

To Reproduce

use leptos::*;

#[server(LocalResourceTest, "/api")]
pub async fn local_resource_test(input: String) -> Result<String, ServerFnError> {
    Ok(input)
}

#[component]
pub fn Test() -> impl IntoView {
    view! { <TestIsland/> }
}

#[island]
pub fn TestIsland() -> impl IntoView {
    let (input, set_input) = create_signal("".to_string());

    let local_resource_test = create_local_resource(move || input(), move |input| local_resource_test(input));

    view! {
        <input style="border: 1px solid black;" type="text" on:input=move |ev| { set_input(event_target_value(&ev)) }/>

        <div>
            <Transition fallback=move || ()>

                {move || match local_resource_test.get() {
                    Some(Ok(result)) => format!("Here is the response from the local resource: {}", result),
                    _ => "".to_string(),
                }}

            </Transition>
        </div>

        {move || format!("Here is the input signal, so you can see it does update and change and should trigger the re-fetch: {}", input())}
    }
}

I’m on my phone because my computer is being used to watch Moana for the 100th time, but if you want to try a local patch or make a PR: leptos_reactive/src/resource.rs needs a source.track() inserted at line 388, just before r.load(). When I fixed #2221 I missed adding the tracking back here in addition to the other helper for resources.

Can you retry against git main @Houski , I merged Greg's commit and am hoping it works for you

Confirmed, latest version at this moment fixes the issue.
