Pipeline documentation missing archiveArtifact documentation

When you go to http://jenkins_install/job/some_pipeline_job/pipeline-syntax/html or https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md  you get a page documenting the DSL in Jenkinsfile.

'archive' is listed as a deprecated step. Users are told to use 'archiveArtifacts' instead, but it's not actually documented anywhere on the page.

Sorry if the component is wrong, it was hard to choose.
