NextCursor field in GetTransformationResult not being sent in response.

Bug report for Cloudinary Go SDK

Before proceeding, please update to the latest version and test if the issue persists

Describe the bug in a sentence or two.

NextCursor is not sent in the reponse for admin.GetTransformation()

Issue Type (Can be multiple)

• Build - Cannot install or import the SDK
• Performance - Performance issues
• Behaviour - Functions are not working as expected (such as generate URL)
• Documentation - Inconsistency between the docs and behaviour
• Other (Specify)

Steps to reproduce

When trying to get the list of derived images from a transform, we do not receive the next_cursor field in the response, so we can never get more derived images after the first call, even with maxResults: 500

	resp, err := cld.Admin.GetTransformation(
		context.TODO(),
		admin.GetTransformationParams{Transformation: t, MaxResults: 1},
	)
	if err != nil {
		fmt.Println(err)
		return nil, err
	}
    fmt.Printf("%+v\n", resp)

that call results in the following (url names have been removed)

&{Name:t_homepage_carousel_card_image AllowedForStrict:true Used:true Named:true Info:[map[crop:fill gravity:face height:390 width:312] map[radius:10]] Derived:[{PublicID:valid/path/1 ResourceType:image Type:upload Format:jpg URL:http://media.validurl SecureURL:https://media.validurl Bytes:11989 ID:xxx}] Error:{Message:}}

There are more than 500 derived images for this transformation, so we will need to be able to paginate these responses.
