Models: documented public methods/attributes to extract best parameters for Auto* models about statsforecast

[yarnabrina]

@AzulGarza @jmoralez , can you please comment on this issue? Is it safe to add a get_fitted_params methon in statsforecast wrapper of sktime relying on model_ attribute, or will you recommend something else?

The same question also applies for neuralforecast probably.

Hey @yarnabrina, sorry for the late reply. I think we can add it on our side, it would probably also fix #774. Just to be sure, these would return the values that are tuned, right? For example for AutoETS it would return model and damped.

Yes, right. That'll help users to specify those themselves in future in case they want to avoid the tuning.
