Subject: [PATCH] Use different IDs for 1) getting the directory of yarn cache
 2) the cache itself (#178)

* Use different IDs for 1) getting the directory of yarn cache 2) the cache itself

Using the current example + https://github.com/actions/cache#skipping-steps-based-on-cache-hit,

I came to a wrong conclusion that I could skip a step
if the `cache-hit` was `true` -
the ID I used was from the wrong step -
the `get yarn cache directory` step,
instead of the `get yarn cache itself` step.

I've updated the example in hopes that it'll be clearer for others aswell!

* Explain which ID to use for `cache-hit` in yarn's example
