flux2: Failed to verify integrity of artifact: artifact has no digest

Describe the bug

Ever since updating from Flux 0.41 to 2.0.1, I’ve been getting these messages sent to my Slack/Discord webhooks everytime it finds and stores a new commit artifact:

gitrepository/flux-system.flux-system
failed to verify integrity of artifact: artifact has no digest

Is there a reason why this shows up? It seems to show up across 6 different Kubernetes clusters, all upgraded from 0.4x versions to 2.0.1.

Steps to reproduce

1. Install Flux
2. Add Slack or Discord webhook notifications
3. Add a GitRepository
4. Push to said GitRepository and wait until Flux sees it

Expected behavior

No integrity message shown.
