Update OpenAI OpenTelemetry integration to pass an ILogger

[eerhardt]

See the conversation at dotnet/eShop#759 (comment)

Today the Aspire integration enables OpenTelemetry unless someone disables tracing:

aspire/src/Components/Aspire.OpenAI/AspireOpenAIClientBuilderEmbeddingGeneratorExtensions.cs

Lines 59 to 61 in 3d3ccd4

	return builder.DisableTracing
	? result
	: new OpenTelemetryEmbeddingGenerator<string, Embedding<float>>(result);

but diffing this code with what's in UseOpenTelemetry(), maybe we need to update it to pass an ILogger in:

https://github.com/dotnet/extensions/blob/576fa221f57f80423a4852e446cee2aa2e937aab/src/Libraries/Microsoft.Extensions.AI/Embeddings/OpenTelemetryEmbeddingGeneratorBuilderExtensions.cs#L36-L43

            loggerFactory ??= services.GetService<ILoggerFactory>();


            var generator = new OpenTelemetryEmbeddingGenerator<TInput, TEmbedding>(
                innerGenerator,
                loggerFactory?.CreateLogger(typeof(OpenTelemetryEmbeddingGenerator<TInput, TEmbedding>)),
                sourceName);
            configure?.Invoke(generator);
            return generator;

That way someone doesn't need to call UseLogging().
