docs(js): Use split layout in Nuxt quick start guides

[inventarSarah]

DESCRIBE YOUR PR

This branch updates the following quick start guides to use the new split layout:

• Nuxt wizard
• Nuxt manual setup
• Nuxt on Cloudflare

I also created new include files for the split layout, which I'll clean up once all guides are updated :)

Closes: #17264

LEGAL BOILERPLATE

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Cursor Bugbot has reviewed your changes and found 1 potential issue.

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Include and heading misplaced inside SplitLayout container
  • I moved the SplitLayout closing tag above the Vite loadEnv include and wrapped the client-side source maps section in its own SplitLayout so only SplitSection children remain inside each layout container.
