title: gitleaks in gitlab ci
body: <p>I am attempting to manually setup gitleaks in GitLab CI to scan my GitLab repo for secrets. I think I've misconfigured my job. The job passes, but outputs a <code>unknown flag 'c'</code> and the gitleaks help dialogue but no expected actual gitleaks-based output.</p>
  
  <p>My `.gitlab-ci.yml' looks like:</p>
  
  <pre><code>stages:
    - security
  
  gitleaks:
    stage: security
    image: zricethezav/gitleaks
    script:
      - gitleaks --verbose --repo-path=$PWD
  </code></pre>
  
  <p>Any suggestion where I might be going wrong?</p>
