Support keyPrefix option of useTranslation

[incleaf]

🚀 Feature Proposal

Input

function Component() {
  const { t } = useTranslation('foo', { keyPrefix: 'bar' })

  t('text1')
  t('text2')
}

Expected output

// foo.json
{
  "bar": {
    "text1": "",
    "text2": ""
  }
}

Actual output

// foo.json
{
  "text1": "",
  "text2": ""
}

Motivation

Currently keyPrefix option is not supported
