Windows CI tests are failing with invalid character ',' looking for beginning of object key string

[mauriciopoppe]

After a few green runs in CI for Windows I saw that the CI jobs failed with the error invalid character ',' looking for beginning of object key string, I checked recent merged PRs and none of them seem to be modifying the Makefile paths related with Windows (the closest PR was #976).

After #986 was merged I saw that the post submit job created the image gcr.io/k8s-staging-cloud-provider-gcp/gcp-compute-persistent-disk-csi-driver:master with these contents for the manifest:

The CI Windows jobs are running and passing again e.g. https://prow.k8s.io/view/gs/kubernetes-jenkins/logs/ci-gce-pd-csi-driver-latest-k8s-master-windows-2019/1529048585277018112 :)
