Khalil Meftah b06ad40888 feat(hub): add pretrained_revision to pin Hub model versions (#3820) ...

- Add pretrained_revision field to PreTrainedConfig (policies) and
RewardModelConfig (reward models), and thread it through make_policy(),
make_pre_post_processors(), and make_reward_model() so that weights and
processor configs can be loaded from a specific Hub commit, branch, or
tag. Defaults to None (latest version, preserving current behavior).
Dataset and env hub loading already supported revision pinning.
