.Net: Support for embedding dimensions

[marcominerva]

Azure.AI.OpenAI NuGet package supports the Dimensions property for embeddings, to set the number of dimensions the resulting output embeddings should have. I see that the latest version of AzureOpenAITextEmbeddingGenerationService in Microsoft.SemanticKernel.Connectors.OpenAI does not provide a way to specify this value.

Is there any ETA about when will this feature be available?
