Typos in some country Arabic names

[Kareem-Zaid]

File with issue: assets/json/country_city.json

When I sorted the Arabic names of countries alphabetically, I noticed that there are some names that have typos:

• Line 14680: " الولايات المتحدة" includes an extra leading space.
• Line 4481: " جزر جوادلوب" includes an extra leading space.
• Line 6068: "Kosovo" is the English name instead of the Arabic one.
• Line 8679: "الجبل الأسو" is missing a character ("الجبل الأسود").
• Line 2995: "الكونغو" is a duplicate Arabic country name, which should be - according to ISO Code "CD" - "الكونغو الديموقراطية".
• Line 2397: "جزر كوكس(كيلينغ)" lacks a space before the first bracket.
• Line 2795: "کوراسائو" first character is not normal "ك", instead it's "ک", which sorts it as the last item in the Arabic alphabetical order.

That's all for now. And thanks for your great effort.
