Spring AI Support for Json Schema with Gemini

The current implementation allows passing a JSON schema to OpenAI using OpenAiChatOptions.setResponseFormat, where a ResponseFormat with a specified JSON schema can be provided. However, this functionality is not available in VertexAiGeminiChatOptions. In the latter, you can only specify the contentType without the ability to include a schema.
