Conflicting type variable count

Reports conflicting partial container declarations due to a mismatch between the number of type variables. Declaring a partial container with a differing number of type variables is an error.

Quick fixes are available to correct the number of type variables declared or navigate to the conflicting declaration.

Example:

# Class 'Example' has 1 type variable which conflicts with other declarations
class Example[A]
end

# Class 'Example' has 2 type variables which conflicts with other declarations
class Example[Y, Z]
end

After the quick fix:

class Example[A, B]
end

class Example[Y, Z]
end
