Saving deps cache on windows

[deemp]

Hi! On a Windows runner, the action saves almost no deps. Here are the last lines of logs (link) for cache/save:

Good catch! I think this is a huge clue in #28.

So, where does Stack place things on Windows? Is this not the correct set of paths?

path: ~/.stack
./rzk-js/.stack-work
./rzk/.stack-work
./.stack-work

As far as I know, choosing this option is all we can control here, the rest is actions/cache/save.

These paths seem relevant (link, link):

~\AppData\Roaming\stack
~\AppData\Local\Programs\stack
