[Docs] Bump Dynamo to 1.6.2 and add retry to Dynamo examples - #4485

In Dynamo 1.5.1, a vLLM prefill worker that loses etcd hangs on exit: its teardown never shuts down the EngineCore child process, so Python blocks joining it (ai-dynamo/dynamo#16401, fixed in 1.6.0). On 1.6.2, the frontend and both workers exit once their etcd leases expire. Since #4474, services with the `dynamo` router accept `retry`. Without it, a failed replica, such as etcd, fails the whole run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
