feat generate translations from a single json file to allow nesting translations by domain or key

[samk-dev]

This will improve:

Maintaining translation files and other modules translation by allowing easy way to nest translations, example like nuxt-zod-i18n or vailbot which require a nested key

{
  "zodI18n": {
    "errors": {
      "invalid_string": {
        "url": "overload by your global translation, original translation: Invalid url"
      }
    }
  }
}
