Property 'next_cursor' does not exist on type 'ResourceApiResponse'

## Bug report for Cloudinary NPM SDK
Before proceeding, please update to latest version and test if the issue persists

## Describe the bug in a sentence or two.
I'm trying to access `next_cursor` from `ResourceApiResponse` and I get the following error:

```bash
Property 'next_cursor' does not exist on type 'ResourceApiResponse'.ts (2339)
```
However the response clearly contains the `next_cursor`:
```Typescript
const response = {
resources: [],
next_cursor: 'NEXT_CURSOR',
rate_limit_allowed: 0,
rate_limit_reset_at: 'TIME',
rate_limit_remaining: 0,
};
```

I'm fetching the images as follows (using SvelteKit):
```Typescript
export async function GET({ params }: RequestEvent): Promise {
const result = await v2.api.resources({
max_results: 1,
next_cursor: params.slug,
});

return json(result);
}
```

And loading the images in my component as follows:
```Typescript

import type { ResourceApiResponse } from 'cloudinary';

let nextCursor: string | null;
let images: ResourceApiResponse;

async function fetchImage(): Promise<ResourceApiResponse> {
const response = await fetch(`/images/${nextCursor ?? ''}`);
images = (await response.json()) as ResourceApiResponse;

nextCursor = images.next_cursor; // <-- ERROR

return images;
}

```
