nit: fix amplify config (#1150)

Update amplify L0 test config to use the amplify LR schedule

<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit

- Chores
- Updated the default configuration for the ESM2 Accelerate recipe to
use the amplify profile, so runs without overrides will now pick up the
amplify defaults.
- Other parameters (training steps, dataset, trainer) remain unchanged
aside from the selected defaults profile.
- This change is limited to the ESM2 Accelerate recipe and does not
affect other recipes.
