docs: fix recommended syntax for getters as reactive data sources

[billyschonenberg]

Description of Problem

With the addition of toValue in vue 3.3, there is a new syntax so we can use getters as reactive data sources. Here is the announcement. https://blog.vuejs.org/posts/vue-3-3#better-getter-support-with-toref-and-tovalue

The example used in the this post is :

// after: more efficient and succinct
useFeature(() => props.foo)

In the api docs:

// getter syntax - recommended in 3.3+
useSomeFeature(toRef(() => props.foo))

Although this section is about toRef(), I think users should be guided that there is a new implementation using getters with toValue

I think the recommended getter syntax should be useSomeFeature(() => props.foo)

Proposed Solution

Update the docs, please see changes.

Thanks!
