Manifest version changed on jan 19th or 20th

[DennisLammers]

Behaviour

Steps to reproduce this issue

1. Use the docker build action (@V3)
2. Build and push the image (in my case: Google Artifact Registry)

Expected behaviour

I would expect a manifest that has a mediaType of application/vnd.docker.distribution.manifest.v2+json (as it used to be before jan 19th/20th)

Actual behaviour

Instead now the manifest reads a mediaType of application/vnd.oci.image.index.v1+json. We use Google Cloud Run and apparently it can not use this mediaType (gives "image not found" warning, might be similar to #768 ?).

Please note that the workflow and Dockerfile have not changed in the past 2 months.

Logs

The github action does not fail, so the provided link to download archive does not work. Please see attached log from the build stage, step "metadata". You can see here a v1 version is created.
