docs(nuxt): Remove duplicated setup instructions (#19422)

The Nuxt Modules page shows the readme as a documentation which can be
confusing as it does not contain all the details. This PR removes all
duplicated content that is also available in the docs and keeps the link
to the docs.

 ## Compatibility
 
@@ -26,102 +26,6 @@ The minimum supported version of Nuxt is `3.7.0` (`3.14.0+` recommended).
 This package is a wrapper around `@sentry/node` for the server and `@sentry/vue` for the client side, with added
 functionality related to Nuxt.
 
-## Manual Setup
-
-### 1. Prerequisites & Installation
-
-1. Install the Sentry Nuxt SDK:
-
-   ```bash
-   # Using npm
-   npm install @sentry/nuxt
-
-   # Using yarn
-   yarn add @sentry/nuxt
-   ```
-
-### 2. Nuxt Module Setup
-
-The Sentry Nuxt SDK is based on [Nuxt Modules](https://nuxt.com/docs/api/kit/modules).
-
-1. Add `@sentry/nuxt/module` to the modules section of `nuxt.config.ts`:
-
-```javascript
-// nuxt.config.ts
-export default defineNuxtConfig({
-  modules: ['@sentry/nuxt/module'],
-});
-```
-
-### 3. Client-side setup
-
-Add a `sentry.client.config.ts` file to the root of your project:
-
-```javascript
-import { useRuntimeConfig } from '#imports';
-import * as Sentry from '@sentry/nuxt';
-
-Sentry.init({
-  // If set up, you can use your runtime config here
-  dsn: useRuntimeConfig().public.sentry.dsn,
-});
-```
-
-### 4. Server-side setup
-
-Add a `sentry.server.config.ts` file to the root of your project:
-
-```javascript
-import * as Sentry from '@sentry/nuxt';
-
-// Only run `init` when process.env.SENTRY_DSN is available.
-if (process.env.SENTRY_DSN) {
-  Sentry.init({
-    dsn: 'your-dsn',
-  });
-}
-```
-
-Using `useRuntimeConfig` does not work in the Sentry server config file due to technical reasons (the file has to be
-loaded before Nuxt is loaded). To be able to use `process.env` you either have to add `--env-file=.env` to your node
-command
-
-```bash
-node --env-file=.env .output/server/index.mjs
-```
-
-or use the `dotenv` package:
-
-```javascript
-import dotenv from 'dotenv';
-import * as Sentry from '@sentry/nuxt';
-
-dotenv.config();
-
-Sentry.init({
-  dsn: process.env.SENTRY_DSN,
-});
-```
-
-## Uploading Source Maps
-
-To upload source maps, you have to enable client source maps in your `nuxt.config.ts`. Then, you add your project
-settings to `sentry` in your `nuxt.config.ts`:
-
-```javascript
-// nuxt.config.ts
-export default defineNuxtConfig({
-  sourcemap: { client: 'hidden' },
-
-  modules: ['@sentry/nuxt/module'],
-  sentry: {
-    org: 'your-org-slug',
-    project: 'your-project-slug',
-    authToken: process.env.SENTRY_AUTH_TOKEN,
-  },
-});
-```
-
