Creates up to 100 Categories in a single request.
The operation fails if the resulting site total would exceed 100 Categories. Each primary-language label must be unique within the site and within the request.
Individual Categories can fail while others succeed. Check each result's itemMetadata.success and itemMetadata.error, and use itemMetadata.originalIndex to match it to the input.
To create a single Category, use Create Category.
