[Bug] Acessing all subfolders with cldAssetLoader doesnt seem to work

# **Bug Report**
Acessing all subfolders with cldAssetLoader doesnt seem to work
## **Describe the bug**

When I define my collection and point it to a Folder that has Subfolders on Cloudinary it doesnt import all the assets but only the ones directly in this folder.

## **Is this a regression?**
Did not use previous versions

## **Steps To Reproduce the error**
1.
in src/content/config.ts add

export const collections = {
galleryImages: defineCollection({
loader: cldAssetsLoader({
folder: 'MainFolder/FolderContainingSubfolders',
}),

2.
When calling

const galleryImages = await getCollection('galleryImages');

error is returned: The collection "galleryImages" does not exist or is empty. Ensure a collection directory with this name exists.

## **Expected behaviour**

All Iamges in all Subfolder of the Folder "FolderContainingSubfolders" should be imported
