aider: Added startup logs to BeaconValidatorsDeriver.

# Aider chat conversation:

USER: Add logs to the startup of the deriver

ASSISTANT: To add logs to the startup of the deriver, we will add logging statements in the `Start` method of the `BeaconValidatorsDeriver` struct in `pkg/cannon/deriver/beacon/eth/v1/beacon_validators.go`.

Here is the *SEARCH/REPLACE* block:

pkg/cannon/deriver/beacon/eth/v1/beacon_validators.go
```go
<<<<<<< SEARCH
	if !b.cfg.Enabled {
		b.log.Info("Validator states deriver disabled")

		return nil
	}

	b.log.Info("Validator states deriver enabled")
=======
	b.log.WithFields(logrus.Fields{
		"chunk_size": b.cfg.ChunkSize,
		"enabled":    b.cfg.Enabled,
	}).Info("Starting BeaconValidatorsDeriver")

	if !b.cfg.Enabled {
		b.log.Info("Validator states deriver disabled")
		return nil
	}

	b.log.Info("Validator states deriver enabled")
>>>>>>> REPLACE
```

This will add a log statement at the start of the `Start` method, logging the chunk size and whether the deriver is enabled.
