Fix cookbook scraper bugs and re-run (#697)

* fix path separator bug in cookbook scraper

* update lockfiles

* add category to image name to avoid conflicts

e.g.
testing/integration/introduction
testing/widget/introduction

* fix form_app symlink

* remove webimages directory

* remove vision_challenge

vision_challenge doesn't build on the dev channel

* update pubspec.yaml in _tool and form_app
