The docs should explain how to disable sourcemaps (or even better have them off by default)

📋 Explain your issue

I've been searching around the docs to try to disable sourcemaps, but I don't see any information on how to do that. I'm using Astro 4 and React 18.

Sourcemaps should really be disabled in production by default, because most people don't want the world to be able to read their code comments, and they don't expect that it's the default behavior.

Astro respects Vite's build.sourcemap configuration option, which can be set in the Astro config file:

// astro.config.mjs

export default {
  vite: {
    build: { sourcemap: true },
  },
};

This should be false by default I believe, so if you're seeing sourcemaps in production, it might be worth opening an issue in the Astro repo with a minimal reproduction.
