[helm-3.18.0] Duplicated upload when using helm cli to upload an image.

when using helmOCI client to upload package with tag, its uploading it twice - once with the tag and another time with the SHA

scenario to reproduce:
1. helm registry login -u myUser -p myPassword myartifactory.com
2. helm create busybox
3. helm package busybox --version 100.100.100
4. helm push busybox-100.100.100.tgz oci://myartifactory.com/sobhe

PUT /api/docker/sobhe/v2/busybox/manifests/sha256:065fa59542e3d2ce4006241e41069e387eb0958235cdec165f9ceaf334228ffd -> 201
PUT /api/docker/sobhe/v2/busybox/manifests/100.100.100 -> 201
----the main point here is: "you guys push the same manifest twice, once by tag and once by digest"

all of this is not happening on the previous versions like 3.17.3
