Phạm Bình An db1542af3d fix(tutor): use legacy syntax for lesson 3.1 #34996
Problem:
- Extmark breaks lesson 3.1 of vim-01-beginner.tutor because when users
  delete the line and put it elsewhere, the extmark doesn't move to the
  put location.
- This doesn't mean the extmark implementation is bad though (note that
  thanks to extmark, for the first time, we can make lesson 2.6 really
  interactive), it's just that the tutor format has never been made for
  kinds of lessons like lesson 3.1, which is why all "expected" in that
  lesson are -1, which also means that lesson is not interactive in the
  first place. Also see lesson 2.1.3 in vim-02-beginner, where the mark
  is just used to mark the first line of the exercise, which also prove
  my point.

Solution:
- For a not-really-interactive lesson like lesson 3.1, just use legacy
  syntax. I borrow the old vimtutor's `--->` to mark the exercises of
  the lesson.
- Less redundant interactive marks also make the json files smaller and
  more maintainable.
