[Bug]: Incorrect sourcemaps in dev

[zardoy]

Which Remix packages are impacted?

• remix (Remix core)
• create-remix
• @remix-run/architect
• @remix-run/cloudflare-workers
• @remix-run/dev
• @remix-run/express
• @remix-run/netlify
• @remix-run/node
• @remix-run/react
• @remix-run/serve
• @remix-run/server-runtime
• @remix-run/vercel

What version of Remix are you using?

1.1.3

What version of Node are you using? Minimum supported version is 14.

16.13.0

Steps to Reproduce

1. Scaffold an app from create-remix
2. Create a loader in app/routes/index.ts:

export const loader = () => {
    // debugger
    return [] // set breakpoint here via IDE
}

3. (in case of vscode): Run Debug: JavaScript Debug Terminal (extension.js-debug.createDebuggerTerminal), run npm run dev in it
4. Open the page

Expected Behavior

• The code will stop the execution in case if debugger is uncommented
• Breakpoint won't bound and I think this might happen because of incorrect paths to source files in sourcemaps. I also suppose stacktrace on errors should show real files paths

Actual Behavior

The code should stop the execution on breakpoints from IDE

Probably #367 already got it covered.

Yes, closing in favor of #367
