Associated nydus image can't be recognized

[imeoer]

If you are reporting a problem, please make sure the following information are provided:

Expected behavior and actual behavior:

Expected: nydus images are compatible with both docker scheme v2 and OCI image spec v1 types of config media type.
Actual: the associated nydus image can't be recognized as a nydus accessor if it using the docker scheme v2 config type.

Steps to reproduce the problem:

1. Convert an OCI v1 image to a nydus image with OCI reference type:

nydusify convert \
  --source 192.168.64.7/library/busybox \
  --target 192.168.64.7/library/busybox:latest-nydus \
  --oci \
  --with-referrer

2. The converted nydus image is not associated with the original OCI v1 image in the harbor portal UI.

Versions:

• harbor version: v2.9
