subject: fix missing media type recognition for nydus (#19453) 

Nydus images are compatible with both docker scheme v2 and OCI image spec v1
types of config media type:

  - application/vnd.oci.image.config.v1+json
  - application/vnd.docker.container.image.v1+json

The patch fixes the media type recognition on the accessory type check.
