`git-lfs` binary not resolving in .git post-checkout hook preventing a number of notebook updates from being published about tutorials HOT 2 OPEN

This could be hard to debug from regular PR until we would fuse test and publish stage proposed in #286

Ultimate resolve may be nuke and rebuild as this repo was created also for this case in mind...

from tutorials.

#286 is a great idea, fully behind it! Nuke and rebuild might be a good idea as well.

In the meantime though, I think it might be worth including the debugging lines I added to "git check and switch branch" step (with or without cat of the log) just so we have more visibility into why precisely the post-checkout hook is failing. The next merged PR could then potentially illuminate the problem before #286 gets implemented or the nuke approach. What do you think?
