Refactor OllamaAPI to Ollama class and update documentation

- Replaced instances of `OllamaAPI` with `Ollama` across the codebase for consistency.
- Updated example code snippets in documentation to reflect the new class name.
- Enhanced metrics collection setup in the documentation.
- Added integration tests for the new `Ollama` class to ensure functionality remains intact.
