Stream wrapper does not support move(), causing issue with creation via JSON:API

Problem/Motivation

Cloudinary's stream wrapper does not support the move operation. I belive this is caused by the fact that \Drupal\cloudinary_stream_wrapper\StreamWrapper\CloudinaryStreamWrapper::stat() does not properly report that the directory/folder exists when drupal prepares the directory in \Drupal\Core\File\FileSystem::move().

I believe the root cause of this issue is that \Drupal\cloudinary_stream_wrapper\StreamWrapper\CloudinaryStreamWrapper::loadResource() does not load directory resources as it should.

Steps to reproduce

Try to create a cloudinary image media entity via Drupal core's JSON:API, and the second request will throw the following error:

The specified file 'temporary://filexkpCkd' could not be copied because the destination directory 'cloudinary://2022-12' is not properly configured. This may be caused by a problem with file or directory permissions.

Example:

# USING JETBRIANS HTTP CLIENT

### Step 1: Upload the image file to drupal with json api.
POST https://example.com
    /jsonapi
    /media
    /cloudinary_image
    /field_media_cloudinary_image
Authorization: Basic username password
Content-Type: application/octet-stream
Accept: application/vnd.api+json
Content-Disposition: file; filename="ReplaceMe.png"

### Step 2: Create the image media entity with the json api, using the file id/uuid from the previous step's response.
POST https://example.com
    /jsonapi
    /media
    /cloudinary_image
Authorization: Basic username password
Accept: application/vnd.api+json
Content-Type: application/vnd.api+json

{
  "data": {
    "type": "media--cloudinary_image",
    "attributes": {
      "name": "REPLACE ME"
    },
    "relationships": {
      "field_media_cloudinary_image": {
        "data": {
          "type": "file--file",
          "id": "c777c1c4-c991-4b82-b60b-018fe2ddc638",
          "meta": {
            "alt": "alt",
            "title": "title"
          }
        }
      }
    }
  }
}

Proposed resolution

Fix \Drupal\cloudinary_stream_wrapper\StreamWrapper\CloudinaryStreamWrapper::loadResource() so it can load file/folder resources from cloudinary.
