feat(nuxt): Add Cloudflare Nitro plugin

[s1gr1d]

⚠️ This PR is a work-in-progress and APIs and naming might change

A plugin which initializes Sentry when deployed to Cloudflare.

1. Remove the previous server config file: sentry.server.config.ts
2. Add a plugin in server/plugins (e.g. server/plugins/sentry-cloudflare-setup.ts)
3. Add this code in your plugin file

   // server/plugins/sentry-cloudflare-setup.ts (filename does not matter)
   import { cloudflareNitroPlugin } from '@sentry/nuxt/module/plugins'
   
   export default defineNitroPlugin(cloudflareNitroPlugin({
       dsn: 'https://dsn',
       tracesSampleRate: 1.0,
   }))

Thanks for working on this! By any chance you wouldn't have a suggestion on how to install this from github with pnpm? Tried,

pnpm add github:getsentry/sentry-javascript#sig/nuxt-cloudflare

but this installs the @sentry package not @sentry/nuxt..
