Issues in examples/.dvcignore

[iesahin]

This is the review of https://www.katacoda.com/dvc/courses/examples/dvcignore

• It repeats itself for data1, data2, data3 files.
• There should be a glob example.
• The command

  cat .dvc/cache/54/40cb5e4c57ab54af68127492334a23.dir \ | python -m json.tool

  should use ˋjqˋ

• The command

  dvc run \ -f stage.dvc \ -o dir/data2 \ 'echo data2 > dir/data2'

  should use a newer version of dvc.yaml tracking. Actually this example is a bit superflous, stages are not tracked by .dvc files now.

There could be 3 examples in 3 pages:

• Ignoring files
• Ignoring directories
• Ignoring by globs
