class ParagraphsBrowserPreviewerWidget in Paragraphs Browser+Previewer 8

Plugin implementation of the 'entity_reference paragraphs' widget.

We hide add / remove buttons when translating to avoid accidental loss of data because these actions effect all languages.

  id = "paragraphs_browser_previewer",
  label = @Translation("Paragraphs Browser Previewer EXPERIMENTAL"),
  description = @Translation("An paragraphs inline form widget with a Browser Previewer."),
