olm.skipRange annotations are missing on dpu-operator, substitutions doesn't work now.
 
To make the annotation showing up needs two things to work together: * the art.yml file

https://github.com/openshift/sriov-network-operator/blob/main/manifests/art.yaml
https://github.com/openshift/dpu-operator/blob/main/manifests/art.yaml
Comparing sriov and dpu operator, they are basically identical, no problem here.
  * below annotation is needed

olm.skipRange: '>=4.3.0-0 <4.21.0'  (4.21 as an example)

 and the code can be found in sriov-operator (https://github.com/openshift/sriov-network-operator/blob/cb240eea07e578c8e21061eff[…]ifests/stable/sriov-network-operator.clusterserviceversion.yaml)

But missing in dpu-operator
https://github.com/openshift/dpu-operator/blob/main/manifests/stable/dpu-operator.clusterserviceversion.yaml this file.
