examples: fixed fault-injection delay demo (envoyproxy#11715)

fault injection example did not work for delay option. After gdb debugging it was discovered that fault injection config requires delay part to be present. Without delay part Envoy assumes that Delay is disabled and does not scan RTDS for delay config updates. Risk Level: Low: Testing: Did manual testing as described in https://www.envoyproxy.io/docs/envoy/latest/start/sandboxes/fault_injection Docs Changes: No Release Notes: No Fixes: envoyproxy#11095 Signed-off-by: Christoph Pakulski <christoph@tetrate.io>
