Windows specific path finding problem

[cansavvy]

No root directory found in C:/Users/runneradmin/AppData/Local/Temp/RtmpER1MgI/Rbuild128c55b62912/leanbuild/vignettes or its parent directories. Root criterion: contains a file "_bookdown.yml"

From: https://github.com/jhudsl/leanbuild/pull/47/checks?check_run_id=3610942536

I don't know what the deal is here. Tried to make sure it wasn't fixed by just a file.path() here and there, but it was not.

I think rprojroot package has some inconsistencies when it comes to windows and we use that a fair amount. https://github.com/r-lib/rprojroot/issues/36

^ I was wrong it's not rprojroot's problem. I think it has to do with the zipping or unzipping of the example files. But I don't know how to fix it.

Why does it think it needs to find this file? I'm not sure.

This should be addressed at the same time as #56 So it no longer needs to be its own issue.
