Feature request

Would like to add a revision parameter in push_to_hub method of a trainer. The same parameter already exists in hub apis. #25578

Motivation

Would like to add tags or versions to the same model after training multiple times, so that it's easier to compare the performance. Adding revision tag will allow me to save multiple versions of same model in the same huggingface repo, instead of creating multiple repos.
