fix(dspy): added copy to OllamaLocal to propagate model, model_type, base_url and timeout_s.

[xyloid]

This problem is very similar to #769. OllamaLocal.copy uses LM.copy. However, OllamaLocal's kwargs dict doesn't have model key, which means model = kwargs.pop("model") will create a KeyError. This fix added a copy method to OllamaLocal class so that it's own attributes like model, model_type, base_url and timeout_s can be copied.

Hi @xyloid , thanks for the contribution! Could you please rebase and merge to the latest version on main? Seems like there was a failing test on our end (nothing wrong with this PR) that just needs an update. Ready to merge after that!
