fix(VTextarea): set overflow:auto when auto-grow

[sunner]

Description

Set overflow from hidden to auto.

If auto-grow and max-rows are used together, the scroll bar should not be hidden.

Markup:

<template>
  <v-container fluid>
    <v-textarea name="input-7-1" variant="filled" label="Label" auto-grow rows="3" max-rows="5"
      model-value="The Woodman set to work at once, and so sharp was his axe that the tree was soon chopped nearly through."></v-textarea>
