Resolved images from kbld not passed through in educates-config config map.

[GrahamDumpleton]

Describe the bug

The educates-config config map in educates namespace has a sections for imageVersions. This provides mappings for locations for images. Before 3.0 refactor for deployment, the mapped to image would have sha reference from kbld for images. This is no longer the case and is now just passed through like:

    imageVersions:
    - name: session-manager
      image: ghcr.io/educates/educates-session-manager:3.1.0-rc.1
    - name: training-portal
      image: ghcr.io/educates/educates-training-portal:3.1.0-rc.1

Consequence is that disconnected installs would no longer work where images were all copied into an internal registry using imgpkg copy.
