What issues does this PR fix or reference?

fixes eclipse-che/che#21353
fixes eclipse-che/che#21502

Is it tested? How?

1. Deploy Eclipse Che with this image: quay.io/eclipse/che-dashboard:pr-567
2. Add defaults(patch checluster/eclipse-che). For example:

  devEnvironments:
    defaultComponents:
      - container:
          image: 'quay.io/devfile/universal-developer-image:ubi8-latest'
          sourceMapping: /projects
        name: universal-developer-image
    defaultEditor: eclipse/theia/next

3. Create a workspace using a GitHub repository without a devfile.
   For example: https://github.com/eclipse-che/che-jwtproxy
4. You should be able to see all default components propagated to the workspace

You can test it with https://eclipse-che.apps.cluster-5s2x5.5s2x5.sandbox995.opentlc.com
