fixes netstandard2.0 bug in embeddings request response types

[prathikr]

E:\_work\1\s\sdk\cs\src\OpenAI\EmbeddingRequestResponseTypes.cs(60,16): error CS8604: 
  Possible null reference argument for parameter 'responseData' in 'EmbeddingCreateResponse EmbeddingRequestResponseExtensions.ToEmbeddingResponse(string responseData, ILogger logger)'. 
  [E:\_work\1\s\sdk\cs\src\Microsoft.AI.Foundry.Local.csproj::TargetFramework=netstandard2.0]

The null check string.IsNullOrWhiteSpace doesn't narrow the nullable type under netstandard2.0's annotations. Needs to be response.Data! to avoid error but we know it's not null or whitespace due to the check above.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Fixes a nullable flow-analysis warning under netstandard2.0 by ensuring response.Data is treated as non-null after an existing guard.

Changes:

• Added a null-forgiving operator (!) when passing response.Data into ToEmbeddingResponse.
