Silence govulncheck (#619)

fix: ignore govulncheck hits

This change should always allow the step to pass even on error.
As the issue are often times fixed in stdlib, we'd have to bump
our go.mod to a certain patch level which is undesirable. Otherwise
having this check fail will always mark the CI pipeline as failed.
