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.

This issue was opened in response to this one being opened in the wrong repo.
