📚 Documentation

In the ModelCheckpoint documentation score_name parameter, it says:

if score_function not None, it is possible to store its value using score_name. See Notes for more details.

However, I cannot find any Notes for this detail.

I suggests adding examples about using score_name and score_function like here

I would love to open a PR for this if that is ok. Or if there are already examples exists, perhaps the links can be added to the documentation.
