Removed adjacency req for Wonders

Wonders won't need to be adjacent to district but they will still require one.

Side effect: they won't show on the construction list unless you already have the required district.

Install: unpack to \Documents\My Games\Sid Meier's Civilization VI\Mods\

Uninstall: delete \Documents\My Games\Sid Meier's Civilization VI\Mods\WondersNoAdjacency (saves with the mod will stop working!)

Raw SQL query used:

UPDATE Buildings SET PrereqDistrict = AdjacentDistrict, AdjacentDistrict = NULL WHERE MaxWorldInstances == 1 AND AdjacentDistrict IS NOT NULL;
