refactor: changes computer signature

[jodarove]

Description

With #57 removing the update, we can refactor the computed.

Before this PR:

const doubleCount = computed({ count }, ({ count }) => count * 2);

After this PR:

const doubleCount = computed([count], (countValue) => countValue * 2);
// or
const doubleCount = computed([count], () => count.value * 2);
