[OCP-Release 4.12] rhel-coreos-8, rhel-coreos-8-extensions : Missing source code repositories

From the OCP 4.12 release image, I pulled the information for all internal images into the JSON. In that JSON file, 3 operators (rhel-coreos-8, rhel-coreos-8-extensions, machine-os-content) have no source code references while all other 180 operators have. ``` ... { "annotations": { "io.openshift.build.commit.id": "", "io.openshift.build.commit.ref": "", "io.openshift.build.source-location": "" }, "from": { "kind": "DockerImage", "name": "quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:822bc2bc6d2bd15262e53c2745d17fd1416633891d69fd8d0df9847bd072da40" }, "generation": null, "importPolicy": {}, "name": "rhel-coreos-8", "referencePolicy": { "type": "" } }, { "annotations": { "io.openshift.build.commit.id": "", "io.openshift.build.commit.ref": "", "io.openshift.build.source-location": "" }, "from": { "kind": "DockerImage", "name": "quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:ebfc5c69cc49f5f1547eecba53ac5bcb9817efc51ecf7e2c608977ea36ff88ae" }, "generation": null, "importPolicy": {}, "name": "rhel-coreos-8-extensions", "referencePolicy": { "type": "" } }, { "annotations": { "io.openshift.build.commit.id": "0f141ce9d349fb30755e3d0d7f9f196a91782957", "io.openshift.build.commit.ref": "", "io.openshift.build.source-location": "https://github.com/openshift/route-controller-manager" }, "from": { "kind": "DockerImage", "name": "quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:2efa8b2051bb7c1573142b24386927f26d77572acdc1bba969588c34aec6b7db" }, "generation": null, "importPolicy": {}, "name": "route-controller-manager", "referencePolicy": { "type": "" } }, ... ``` Where are the source codes for those operators?
