Missing time zone i18n for Rails 8.1.x zones America/Nuuk and America/Asuncion

Rails 8.1.x / Activesupport 8.1.x adds/renames IANA identifiers in ActiveSupport::TimeZone::MAPPING to include America/Nuuk and America/Asuncion.

When using Worldwide’s timezone translations with Rails’ time_zone_options_for_select (as shown in Worldwide readme), upgrading from Rails/ActiveSupport 8.0.4 → 8.1.2 raises missing translation errors because Worldwide does not include keys for these identifiers.

Environment

• Rails version 8.1.2
• Worldwide version 1.21.1
• config.i18n.raise_on_missing_translations = true

<%= form.ui_select :timezone,
      time_zone_options_for_select(
        @shop.timezone.name,
        nil,
        Worldwide::TimeZone
      ),
      {},
      label: t('shop_identity.views.admin.settings.general.timezone_label') %>

With raise_on_missing_translations, this emits errors after upgrading from Activesupport 8.0.4 -> 8.1.2.

ActionView::Template::Error: Translation missing: en.timezones.America/Asuncion

Start with Worldwide’s timezone translations used by time_zone_options_for_select and compare them with ActiveSupport::TimeZone::MAPPING in activesupport/lib/active_support/values/time_zone.rb. Reproduce the Rails 8.1.2 case with raise_on_missing_translations=true; done means America/Nuuk and America/Asuncion no longer produce missing translation errors.
