operator status is ready before it's able to accept admission webhooks.

I have a script that attempts to install the operator and create a db that looks something like:

```
kubectl apply -f https://raw.githubusercontent.com/cockroachdb/cockroach-operator/v2.10.0/install/crds.yaml
kubectl apply -f https://raw.githubusercontent.com/cockroachdb/cockroach-operator/v2.10.0/install/operator.yaml
kubectl wait --for=condition=Ready pods --all -n cockroach-operator-system --timeout=5m

kubectl apply -k ./overlays/cockroach
```

Results in:
```
customresourcedefinition.apiextensions.k8s.io/crdbclusters.crdb.cockroachlabs.com created
namespace/cockroach-operator-system created

```

Is there a better way to wait for the operator to be ready before trying to create crdb resources?

Start by reproducing the sequence using install/crds.yaml, install/operator.yaml, and the kubectl wait command shown in the issue. Inspect the operator pod, webhook service, and admission webhook readiness behavior; done means the documented or implemented readiness check prevents CRDB resources from being submitted until admission webhooks accept them.
