OCPBUGS-94072: operator: add startupProbe to nmstate-operator deployment

[mkowalski]

What this PR does

Adds a startupProbe to the nmstate-operator container (deploy template + bundle CSV + ART manifests) and removes initialDelaySeconds from its readiness/liveness probes — the same pattern PR #759 applied to the webhook and kube-rbac-proxy operand containers.

Why

The OCPBUGS-94072 fix shipped in 4.20.29 is incomplete: the customer is still down on 4.20.30/4.20.32, now with the operator pod in CrashLoopBackOff (900+ liveness kills observed in the must-gather host journals). The operator container gets only ~40s to bind :8081 (initialDelay 10s, period 10s, failureThreshold 3), while measured startup in the affected environment is 50–75s. The webhook/metrics pods — which did get startupProbes — recover fine in the same environment, proving the pattern works. Because the operator deployment is CSV-managed, OLM reverts any manual probe edits and marks the CSV Failed/NeedsReinstall.
