Talking Clock Example is outdated

[afscrome]

The talking clock example at https://aspire.dev/architecture/resource-examples/#example-custom-resource---talking-clock is oudated

• It uses obsolete LifecycleHooks
• It uses the obsolete BeforeResoruceCreated event
• It doesn't demonstrate the OnInitializeResource event which is specifically for custom resources.

Latest version is at https://github.com/dotnet/aspire/blob/main/playground/CustomResources/CustomResources.AppHost/TalkingClockResource.cs
