[Bug] Block style (like `|`) is removed in array elements

[PierrePIRONIN]

When a block style | is used in an element of an array, it is removed by the generation.

For example, the following snippet

    targets:
      - libs:
        - |
          package lib.exclude_update

          is_update(review) {
              review.operation == "UPDATE"
          }
        - |
          package lib.exempt_container

          is_exempt(container) {
              exempt_images := object.get(object.get(input, "parameters", {}), "exemptImages", [])
              img := container.image
              exemption := exempt_images[_]
              _matches_exemption(img, exemption)
          }

          _matches_exemption(img, exemption) {
              not endswith(exemption, "*")
              exemption == img
          }

          _matches_exemption(img, exemption) {
              endswith(exemption, "*")
              prefix := trim_suffix(exemption, "*")
              startswith(img, prefix)
          }

results into

  targets:
    - libs: 
        - package lib.exclude_update
        
        is_update(review) {
            review.operation == "UPDATE"
        }
        - package lib.exempt_container
        
        is_exempt(container) {
            exempt_images := object.get(object.get(input, "parameters", {}), "exemptImages", [])
            img := container.image
            exemption := exempt_images[_]
            _matches_exemption(img, exemption)
        }
        
        _matches_exemption(img, exemption) {
            not endswith(exemption, "*")
            exemption == img
        }
        
        _matches_exemption(img, exemption) {
            endswith(exemption, "*")
            prefix := trim_suffix(exemption, "*")
            startswith(img, prefix)
        }
