`NSArray` is not recognized in the generated file

Issue:
one of NSTimeZone.h functions returns NSObject instead of NSArray in the generted code.
@property (class, readonly, copy) NSArray<NSString *> *knownTimeZoneNames;

Actual:
static objc.NSObject getKnownTimeZoneNames() {}
Expected:
static objc.NSArray getKnownTimeZoneNames() {}

Found the issue. CXTypeKind and CXCursorKind are huge enums with a lot of cases to check, and I've just been adding missed cases one by one as we find them. This was one of those missing cases. Surprised it didn't show up earlier, cos it's been a while since I had to add one of these cases. I don't know what's special about knownTimeZoneNames that means it should show up in the AST as a CXType_ObjCObject instead of a CXType_ObjCInterface like every other type I've seen. Anyway, the fix is a one liner.

Interestingly, seems loosely related to #209
