fix: add missing seed parameter to ollama input

Current ollama interfacing does not allow for seed, which is supported in https://github.com/ollama/ollama/blob/main/docs/api.md#parameters and https://github.com/ollama/ollama/blob/main/docs/modelfile.md#valid-parameters-and-values

This resolves that by adding in handling of seed parameter.

     - `temperature` (float): The temperature of the model. Increasing the temperature will make the model answer more creatively. Default: 0.8. Example usage: temperature 0.7
