Multi-platform image created with skaffold build is not sent to default-registry

[renzodavid9]

Expected behavior

When running skaffold build --platform=linux/arm64,linux/amd64 --default-repo=gcr.io/my-registry, Skaffold should push the created multi-platform image to the specified default-repo.

Actual behavior

Instead, it tries to push it to the local Docker engine, which does not support multi-platform images. To make it work, the command should be run with the --push flag: build --platform=linux/arm64,linux/amd64 --default-repo=gcr.io/my-registry --push
