build: Fix nx cache outputs

[mydea]

After this annoying me for quite some time, I finally figured out what the problem with our build was - we had our nx cache outputs wrong. This lead to conflicts when caches were restored etc.

Now, this should be more narrow & correct in what it caches per step, leading to caching actually working (hopefully..)
