Organizations__ContractVersion is an enumerated list of organization contract versions.

This enumerated datatype is used by three input datatypes: AddLimitInput, which is used by the addLimit() mutation field; OrganizationLimitsInput, which is used by the updateOrganizationLimits() mutation; and UpdateLimitInput, which is used by the updateLimit() mutation but that's been deprecated and replaced by updateLimitV2().

This datatype is also used by the datatype, OrganizationLimits, which is used by other datatypes and thereby many more query fields.
