Updated OllamaFunctionTool.toString to reflect what the Ollama API actually wants

Added @NotNull annotation to OllamaFunctionTool.name and OllamaFunctionTool.parameters since the documentation reports as these being required

Made sure that OllamaFunctionTool.description is actually optional as the Ollama API docs define
