docs: This allows you to reposition a list relative to the other lists in
          the project. A list with position 1 will show up at the top of the
          page. Moving lists around lets you prioritize. Moving a list to a
          position less than 1, or more than the number of lists in a project,
          will force the position to be between 1 and the number of lists
          (inclusive).
