Add production instructions to the Quick Start Guide

[rusmux]

Describe the bug

In the Quick Start Guide the instructions are for development only (pnpm run dev). When trying to create a production build (pnpm build && pnpm preview) I encountered a CORS error (#3199), and after fixing it, 404 error codes (#2528). After spending some time searching through the issues list, I fixed these issues, however, I think it would be useful to add production instructions (add headers, change public path), or at least mentions, to the guide

Used Package Manager
