There are no Skolt Sami (language code: sms) map tiles in Kartographer. Likely because missing configurations

Example for Utsjoki:

• https://maps.wikimedia.org/osm-intl/16/37687/14716.png?lang=fi (uses correct label: Utsjoki)
• https://maps.wikimedia.org/osm-intl/16/37687/14716.png?lang=se (uses correct label: Ohcejohka )
• https://maps.wikimedia.org/osm-intl/16/37687/14716.png?lang=sms (uses failback label: Utsjoki)

Expected result for Utsjoki label in Skolt Sami is "Uccjokk"
