Leak: the chart registry password is shown in clear text on step-promote-helm-release error

On the first release of a PHP quickstart, I've got this error where I saw the credentials for the helm chart repo in clear text:

> Showing logs for build my-org-php-test-master-2 stage pipeline and container step-promote-helm-release     releasing chart php-test    error: failed to create chart release in dir charts/php-test: failed to publish: failed to run 'curl --fail -sS -u admin:\ --data-binary @php-test-0.0.1.tgz [http://jenkins-x-chartmuseum.jx.svc.cluster.local:8080/api/charts](http://jenkins-x-chartmuseum.jx.svc.cluster.local:8080/api/charts)['](http://jenkins-x-chartmuseum.jx.svc.cluster.local:8080/api/charts') command in directory 'charts/php-test', output: 'curl: (22) The requested URL returned error: 409 Conflict'
