Deprecate references to custom evaluate_performace function in favor of utilsforecast.evaluation.evaluate?

Description

Many instances throughout the statsforecast docs have the user create a custom evaluate_performace function, but there is a perfectly fine one within utilsforecast, which is installed with statsforecast.

Suggest deprecating references to the custom function in favor of using the evaluate function. Let me know your thoughts.

Hey @quant5, thanks for raising this. We're aware of that but that section was copy-pasted so many times that we haven't found the time to fix them all. We'd welcome a contribution if you're interested.

I can work on this and submit a PR. Likely over the weekend.
