Rename signals with computed when defining custom features with input for consistent naming with withComputed feature.

function withN() {
  return signalStoreFeature(
    {
-      signals: type<{ l: Signal<number>; m: Signal<number> }>(),
+     computed: type<{ l: Signal<number>; m: Signal<number> }>(),
    },
    withComputed(({ l, m }) => ({
      n: computed(() => l() + m()),
    }))
  );
