fix/css export

Never actually tested the exported css file in the previous package before. It actually doesn't work because of the import path. So now I use rollup to copy the index.css over into the dist folder and replaced the url path with a relative path to the fonts/inter.css in the same dist folder.

Also tried to look into have a file path based export so devs can drill into /Actions or /DataDisplay to grab components but that seem more work than its worth.
