chore: update payload_attributes event test data (#8308)

**Motivation**

This is required to pass spec tests since spec example was updated in
ethereum/beacon-APIs#550

**Description**

Update `payload_attributes` event test data

**Note:** we already emit all required fields, no changes needed there
