[🐞] tracking ReadonlySignal directly doesn't infer proper types

[maiieul]

Which component is affected?

Types

Describe the bug

With

    const signal1 = useSignal("signal1") as ReadonlySignal<string>;
    const signal2 = useSignal("signal2");
    useTask$(({ track }) => {
      const tracked = track(signal1);
      signal2.value = tracked;
    });

type of tracked will be ReadonlySignal<string> instead of string. With a Signal<string>, the type of tracked is properly infered as string.

Even though ReadonlySignal was deprecated it should still work in this case.

I think the solution is to have readonlysignal extend Signal
