Country option value (Address element)

Problem/Motivation

Do not translate option value for County element of the Address!

Steps to reproduce

1. Add element Address to the webform.
2. View the webform in different website languages and check the country option value.

Proposed resolution

Country option value should be the same for all language versions of the website. Translate only the label, not the option value!

Solution proposal example:

function hook_webform_options_country_names_alter(array &$options, array $element = []): void {
  /** @var \Drupal\Core\Locale\CountryManagerInterface $country_manager */
  $country_manager = \Drupal::service('country_manager');
  $countries_en = $country_manager->getList('en');

  // Set the option value to "ISO code + English name of the country" (e.g. CZ Czechia) and keep the translation of the labels according to the language version of the website
  foreach ($countries_en as $code => $label_translated) {
    $label_en = $label_translated->getUntranslatedString();
    $options["$code $label_en"] = $label_translated;
  }
}
