 * Runtime binding for the `DeregisterTargets` operation (IAM action

 * Deregisters targets from the bound target group at runtime — the target
 * enters `draining` and is removed once in-flight requests complete. Pairs
 * with {@link RegisterTargets} for custom blue/green orchestration or
 * graceful self-removal on shutdown.
 * Provide the implementation with

 * ### Dynamic Target Management
 * **Example:** Drain an IP target
 * ```typescript
 * // init — bind the operation to the target group
 * const deregisterTargets = yield* AWS.ELBv2.DeregisterTargets(targetGroup);
 *
 * // runtime — start draining the target
 * yield* deregisterTargets({
 *   Targets: [{ Id: "10.0.1.15", Port: 8080 }],
 * });
