Fixes #4506 - Add fsnotify-0.3.0.1 to snapshot.yml

lts-11.22 includes fsnotify-0.2.1.1, which listens to Modify events on
Linux rather than CloseWrite events. For many applications the
difference is neglible because writing a file will result in both
events, but if you run stack inside of docker on Mac this breaks
the --file-watch option because the file sharing integration only
emits Modify events, never CloseWrite events.

fsnotify-0.3.0.1 changed to listen to Modify events rather than
CloseWrite events. Switching to the new version fixes the issue.
