iframe URL ignores baseURL

[codehead]

🐛 The bug

Comments on issue #237 seem to indicate that PR #386 would allow the iframe to be relative to baseURL, but the iframe still points to /__nuxt_devtools__/client/ - this makes nuxt devtools go 404 when the application is accessed through a reverse proxy.

🛠️ To reproduce

https://stackblitz.com/edit/nuxt-starter-s8vyfn?file=nuxt.config.ts

🌈 Expected behavior

Setting baseURL=/prefix/ in nuxt.config.ts

export default defineNuxtConfig({
  app: { baseURL: '/prefix/' },
  devtools: { enabled: true },
});

the iframe should point to /prefix/__nuxt_devtools__/client/ but opening the browser's network monitor or DOM inspector will show that it still points to /__nuxt_devtools__/client/

same for me!

Also seeing a 404 when launching the dev tools. Fixing this would be super useful as we are currently unable to use the dev tools for a project that is hosted under a prefix URL.

Great work. Thank you!
