fix(puzzletron): correct val_dataset_name from 'valid' to 'validation'

[TheSabari07]

The validate_model_defaults.yaml file has val_dataset_name set to valid, but it should be validation per the dataset split expected by the tutorial configuration.

This causes the Puzzletron tutorial to fail at the subblock scoring step (6/8).

What does this PR do?

Type of change: Bug fix

Updates the Puzzletron validation config to use the correct validation dataset split name:

• val_dataset_name: valid → val_dataset_name: validation

This fixes the tutorial configuration so the pipeline can proceed correctly during the validation/subblock scoring stage.

Usage

No user-facing API changes. This is a config fix for the existing Puzzletron tutorial.

Testing

Verified the YAML config was updated to use the correct dataset split name.
