refactor!: replace hilbish.xdg with hilbish.userDir

"xdg" is basically a linux specific thing and it acted linux specific also.
so replace that with a more portable and general "userDir" table

config is for the user's config directory and also defaults to xdg vars on linux.
data is a directory to store data, mostly for scripts.
on other oses beside linux, it is just the config directory for now
