Issue:
[Test]: improve robustness of Operator Unavailable E2Es on Openshift
### Is there an existing issue already for this bug?

- [x] I have searched for an existing issue, and could not find anything. I believe this is a new bug.

### I have read the troubleshooting guide

- [x] I have read the troubleshooting guide and I think this is a new bug.

### I am running a supported version of CloudNativePG

- [x] I have read the troubleshooting guide and I think this is a new bug.

### Contact Details

_No response_

### Version

trunk (main)

### What version of Kubernetes are you using?

1.34

### What is your Kubernetes environment?

Other

### How did you install the operator?

OLM

### What happened?

In `test operator_unavailable_test.go`, we delete both the primary and the operator concurrently, and then we assert that once a new operator pod comes back, it is able to perform a "pending" failover.

The way we check for the operator to be back should be improved, because it can fail in OpenShift if there are other unrelated pods inside the `openshift-operators` namespace.

### Cluster resource

### Relevant log output

### Code of Conduct
