Using a local model

Install Ollama and run it locally
Inside application.properties, configure the model that you are running inside Ollama (default is spring.ai.ollama.chat.model=llama3.2)
Inside pom.xml, change the dependency spring-ai-openai-spring-boot-starter into spring-ai-ollama-spring-boot-starter
Run all the tests (some will not be working as some of the features are not supported by local models)
