// Gets information about all versions of a slot type. The GetSlotTypeVersions
// operation returns a SlotTypeMetadata object for each version of a slot type. For
// example, if a slot type has three numbered versions, the GetSlotTypeVersions
// operation returns four SlotTypeMetadata objects in the response, one for each
// numbered version and one for the $LATEST version. The GetSlotTypeVersions
// operation always returns at least one version, the $LATEST version. This
// operation requires permissions for the lex:GetSlotTypeVersions action.
