Collapse upload artifacts

[rpl-ffl]

        post {
        always {
            script {
                def artifacts = ["*.yml", "*.csv", "*.log", "*.html"]
                uploadArtifacts(artifacts)
            }
        }
    }

should now reads:

    post {
        always {
            uploadArtifacts(["*.yml", "*.csv", "*.log", "*.html"])
        }
    }
