Fix OptionsProvider test

Currently the test complains about:

    Array to string conversion
    
    /builds/project/ip2country/tests/src/Kernel/OptionsProvider/OptionsProviderTest.php:59

Let me revert my first attempt at a fix (8c155dee469c7be6b1) to figure out what exactly the initial problem was.

(Just for the record)
The error is (truncated, because there are over 200 countries):

--- Expected
    +++ Actual
    @@ @@
     Array (
    -    'AF' => 'Afghanistan'
    -    'AL' => 'Albania'
    -    'DZ' => 'Algeria'
   +    'AF' => Drupal\Core\StringTranslation\TranslatableMarkup Object (...)
   +    'AL' => Drupal\Core\StringTranslation\TranslatableMarkup Object (...)
   +    'DZ' => Drupal\Core\StringTranslation\TranslatableMarkup Object (...)

So in short the core country.manager service is now returning markup objects instead of the country names.

That fixed the markup issues, and exposed a core change made in 📌 Update the countries list to latest Unicode CLDR version 44 Fixed which changed the spelling of one country name (Turkey =>Türkiye) and added a new country (Sark).

That fixed the OptionsProvider tests in D10 and D11. Merged.

Automatically closed - issue fixed for 2 weeks with no activity.
