🔧 Add KernelMemory class and update TestRunner

Added a new class KernelMemory to the LLama.Examples.NewVersion namespace, which includes a Run method that demonstrates the usage of Semantic Kernel Memory. The class imports a sample PDF document and asks a question to the memory, displaying the answer and relevant sources.

Updated the TestRunner class in the same namespace to include an option (choice 15) to run the KernelMemory example.

🔧 Fix typo in LLamaSharpTextEmbeddingGeneration class

Fixed a typo in the LLamaSharpTextEmbeddingGeneration class where the LlamaSharpConfig variable was incorrectly named as LlamaSharpConfig.

Added XML documentation for the LLamaSharpTextEmbeddingGeneration constructor, Dispose method, and GenerateEmbeddingsAsync method.
