PUBLIC_FOLDER_PATH to set output directory

[kattjevfel]

I originally started writing this as a "doesn't work" ticket, but figured I had just misunderstood its purpose, so here is a feature request instead.

Currently, setting PUBLIC_FOLDER_PATH only changes where the internal webserver looks for static files.
What I'd like to see is it also being used for picking where the files get generated, instead of being hardcoded:

lewd2/packages/frontend/build.js

Line 11 in a25241e

outDir: "./dist/js",

lewd2/packages/frontend/build.js

Line 18 in a25241e

outDir: "./dist/css",

Reasoning behind wanting to put it elsewhere is so it can be accessed by another linux container via a bind mount.
Another reason would be to load the public folder with 2TB of waifus and not want that on my root drive.

EDIT: Found out that it also doesn't like inputting full paths either:
