fix: Swap transform/object and observek8sattributes processors (#255)

The observek8sattributes processor might edit the log body in-place,
which might affect the value of facets computed by transform/object.

Therefore, we swap the two processors in the pipeline to make sure
observek8sattributes always acts before transform/object.
