How do I set up provenance and attestations for Loki?

    // Example setup for provenance and attestations in Loki

    // Step 1: Define your Loki configuration
    loki:
      configs:
        - name: default
          target: loki
          static_configs:
            - targets: ['localhost:3100']
              labels:
                environment: production

    // Step 2: Set up provenance logging with the following fields
    provenance:
      enabled: true
      logLevel: debug
      fields:
        - application: my-application
        - version: 1.0.0
        - commit: abcdef123456

    // Step 3: Add attestations for critical logs
    attestations:
      enabled: true
      sources:
        - name: trusted_source
          url: https://my-trusted-source.com/attestations
      verification:
        algorithm: sha256

    // Step 4: Integrate with your CI/CD pipeline for automatic logging
    // Add the following step in your pipeline configuration
    steps:
      - name: Check Logs
