## What this PR does
Increases the `startupProbe.failureThreshold` for kube-apiserver
container from 3 to 30.
The default 30 seconds (3 failures × 10s period) is often insufficient
for kube-apiserver to complete RBAC bootstrap, especially:
- Under high load conditions
- With slower etcd connections
- During initial cluster provisioning
This change gives kube-apiserver up to 300 seconds to initialize,
preventing unnecessary CrashLoopBackOff cycles.
