Keycloak 17.0.0 image is missing a proper manifest, causing pulls to fail with older versions of Docker

The following command fails to pull Keycloak:

sudo docker pull registry1.dso.mil/ironbank/opensource/keycloak/keycloak@sha256:876a41ea7f7f6362176a2a2baff9e030ab77fda7df324df62336df9424d8b796

This command results in the following error message in CentOS with Docker version 1.13.1, build 7d71120/1.13.1:

Trying to pull repository registry1.dso.mil/ironbank/opensource/keycloak/keycloak ... 
manifest for registry1.dso.mil/ironbank/opensource/keycloak/keycloak@sha256:876a41ea7f7f6362176a2a2baff9e030ab77fda7df324df62336df9424d8b796 not found

But, it succeeds in Ubuntu with Docker version 20.10.9, build c2ea9bc. Newer versions of the Keycloak image appear to be unaffected by this issue.
