docker pull fails in docker-in-docker v3

[georgewitteman]

After v3.0.0 (commit a646de4, PR #1645), docker pull / docker compose pull inside the docker-in-docker container fails to extract image layers that contain whiteout files, with:

failed to extract layer (application/vnd.oci.image.layer.v1.tar+gzip sha256:…)
to overlayfs as "extract-…":
failed to convert whiteout file "etc/alternatives/.wh.pager.1.gz":
operation not permitted

I'm having a (I assume) related issue using docker-in-docker:3 with Aspire, failing to extract the mcr.microsoft.com/azure-storage/azurite:3.35.0 image):
