Make the publication tab more generic to allow both its customization and refresh automatically

The goal is to customize a publication tab and still get it to refresh automatically:
A Studio tab is created, made of a container containing a template (nuxeo/nuxeo-features/nuxeo-platform-rendition/nuxeo-platform-rendition-publisher/src/main/resources/web/nuxeo.war/incl/tabs/document_publish.xhtml copied as widgets/document_publish.xhtml) and a form layout.
With this setup, one observes that the tab content is not refreshed upon publishing/depublishing the document.

To ensure the tab content to be refreshed automatically upon publishing/unpublishing the document, one solution found is to replace in 3 places in nxserver/nuxeo.war/incl/tabs/document_publish_template.xhtml

render=":publishTreeForm:publishingInfoList facesStatusMessagePanel"

with

render="@form facesStatusMessagePanel"
