Multi-arch images for `devel-centos8` do not offer `ppc64le` in 11.0 and 11.1

It looks like 11.0 and 11.1 do not provide ppc64le in their manifest for devel-centos8:

$ docker manifest inspect --verbose nvidia/cuda:11.0-devel-centos8 | grep architecture
			"architecture": "amd64",
$ docker manifest inspect --verbose nvidia/cuda:11.1-devel-centos8 | grep architecture
			"architecture": "amd64",

Interestingly, older and newer versions do:

$ docker manifest inspect --verbose nvidia/cuda:10.0-devel-centos7 | grep architecture 
				"architecture": "amd64",
				"architecture": "ppc64le",
$ docker manifest inspect --verbose nvidia/cuda:11.2.0-devel-centos8 | grep architecture
				"architecture": "amd64",
				"architecture": "ppc64le",
				"architecture": "arm64",

Is this intended or an oversight? Thanks!
