feat(useTextareaAutosize): new function

[innocenzi]

Description

This function makes it easy to make a textarea automatically grow depending on its content. This is something not easily achievable when not knowing the underlying trick.

<script setup lang="ts">
const { textarea, input } = useTextarea()
</script>

<template>
  <textarea
    ref="textarea"
    v-model="input"
    class="resize-none"
    placeholder="What's on your mind?"
  />
</template>

Could we also have a directive version of it?

That would be nice, but I didn't manage to properly test it when I tried to make one, I have no experience with directives. I may try to PR one in the future though, if that's okay?
