Some Azure and Open AI chat client integrations automatically add `OpenTelemetryChatClient`:

* https://github.com/dotnet/aspire/blob/d217f76a9302421d23d82c65085604ba7f16a58a/src/Components/Aspire.OpenAI/AspireOpenAIClientBuilderChatClientExtensions.cs#L76
* https://github.com/dotnet/aspire/blob/d217f76a9302421d23d82c65085604ba7f16a58a/src/Components/Aspire.Azure.AI.Inference/AspireAzureAIInferenceExtensions.cs#L215

However there are settings on `OpenTelemetryChatClient` - notably `EnableSensitiveData` - that can't be configured. `EnableSensitiveData = true` adds important information, such as the prompts sent to the AI system, that is useful during development. There should be some way to configure the OTEL client.

### Describe the solution you'd like

MEAI provides an action to configure the OTEL client:

https://github.com/dotnet/extensions/blob/9e041fff9a8c06efce8dd335de03868ff9ee8556/src/Libraries/Microsoft.Extensions.AI/ChatCompletion/OpenTelemetryChatClientBuilderExtensions.cs#L26-L30

An optional argument like this could be added to the helper extension methods that register the client.
