Run make test_trivy_repo TRIVY_EXIT_CODE=1
  make test_trivy_repo TRIVY_EXIT_CODE=1
  shell: /usr/bin/bash -e {0}
make: *** No rule to make target 'test_trivy_repo'.  Stop.
Error: Process completed with exit code 2.

This will fail as long as this commit is not merged into release as the Makefile on the release branch currently has no test_trivy_repo target.
