In the "Files changed" tab, it is displaying the following message:

GitHub Actions
/ integration-tests / Scan Image (ghcr.io-canonical-jenkins-41c7d3489ea531517dfeaa008d190147ff480dcd-_1.0_amd64.tar)

CVE-2024-47072 not present anymore, can be safely removed.

I think we can try removing line 2 from .trivyignore, and see if it still works.

Else the PR is fine.
