Code Review
This pull request removes the default value for the rollout selection, making it a mandatory configuration parameter. This is a breaking change, and it is implemented correctly by using the ??? placeholder in the Hydra configuration files. The associated test script has been updated to reflect this change.
My main concern is that two of the modified YAML files, _generated_ppo_megatron_trainer.yaml and _generated_ppo_trainer.yaml, appear to be auto-generated. Modifying generated files directly can lead to maintenance issues, as these changes might be lost when the files are regenerated. The source of these files should be updated instead.

The _generated_ prefix in the filename suggests this file is auto-generated. Manually editing generated files is generally discouraged as these changes can be accidentally overwritten when the generation script is run again. To ensure this change is permanent, please consider modifying the source that generates this file.
