    The setting `features: { trackRevisions: true }` adds an element `<w:trackRevisions />` to the `settings.xml` file.    This specifies that the application shall track *new* revisions made to the existing document.    See also https://docs.microsoft.com/en-us/dotnet/api/documentformat.openxml.wordprocessing.trackrevisions
    Note that this setting enables to track *new changes* after teh file is generated, so this example will still    show inserted and deleted text runs when you remove it.*/
