Disable the readiness probe

Our terminationGracePeriodSeconds is set to 600 by default. However,
since the readinessProbe will start failing immediately after the
manager shutdown is initiated, any remaining work will be terminated
once the readiness probe failure threshold is reached (30s by default)
and the pod will receive another SIGTERM.

This change removes the readinessProbe configuration and allows the
helm-controller manager to correctly handle graceful termination without
being interrupted by the readinessProbe failure.
