Use docker engine for container build make targets in release GHA

[rooftopcellist]

- engine defaults to podman, but podman does not support all docker
  buildx features at the moment
- for now, we can solve this by using docker everywhere in this workflow
- fix galaxy-operator image refs in CSV

I have re-pushed 1.0.0 and 1.0.1 with these changes and confirmed that the full image is now present in the resulting CSV in the bundles.

Before:

$ opm alpha bundle unpack quay.io/ansible/eda-server-operator-bundle:1.0.1
$ cat manifests/eda-server-operator.clusterserviceversion.yaml | grep image: | grep eda-server-operator:1.0.1
                image: eda-server-operator:1.0.1

After:

$ opm alpha bundle unpack quay.io/ansible/eda-server-operator-bundle:1.0.1
$ cat manifests/eda-server-operator.clusterserviceversion.yaml | grep image: | grep eda-server-operator:1.0.1
                image: quay.io/ansible/eda-server-operator:1.0.1
