Fix incorrect URL to wet-boew.min.js

This was broken by me in my earlier fix to #29 in commit 675c312

https://wet-boew.github.io/themes-dist/GCWeb/wet-boew/js/wet-boew.min.js
remained in its original URL, i.e. did not get moved one directory level
down unlike the other assets.

Thanks to @jvanulde for the heads up!
