Thank you for working on this PR @mmorel-35 Overall it looks good to me. I only suggested reusing existing workflow definition file to add linter step.

Please squash and sign-off your commits as well.

In .github/workflow/build.yaml we already defined a workflow to do static analysis of source code on each PR.
Instead of adding another YAML, could we run golangci-lint action as a step under the verify-code job? This way we'll group checks and workflow triggers in one place.
