Patching ovn image is failing

[venkataanil]

Currently scale-ci-deploy is using below command to patch ovn image

oc -n openshift-network-operator set env deployment.apps/network-operator OVN_IMAGE={{openshift_ovn_image}} RELEASE_VERSION="5.0.0"`

Howerver this patching is failing because of specifying RELEASE_VERSION.
network-operator pod is stuck in "CrashLoopBackOff" state

We are not sure why we are overriding RELEASE_VERSION when we only want OVN_IMAGE to get overriden. To fix this issue we should only override OVN_IMAGE when user wanted ovn patching.
