Add Kosovo in list of countries

[Kristina Hoeppner]

In Mahara, we use https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 for our list of countries. We use the officially assigned code elements but not necessarily temporary or other elements.

Kosovo is missing in the country list in Mahara and should be added as it is recognized in Europe.

Bug 1731793: Add Kosovo into the list of countries

Kosovo is not yet in the official list of country
codes and hence was not in Mahara yet. We add the
temporary country code so it is included.
