Improve setup steps on deploying Nuxt app to AWS Amplify on docs

Affected page

Description

The documentation states that the integration of a Nuxt 3 app with AWS Amplify requires zero configuration. But that is not the case and I'll explain why.

The default build config that AWS Amplify generates is this:

version: 1
frontend:
  phases:
    preBuild:
      commands:
        - nvm use 18
        - corepack enable
        - npx --yes nypm i
    build:
      commands:
        - yarn run build
  artifacts:
    baseDirectory: .amplify-hosting
    files:
      - '**/*'

However, Nuxt's build (and generate) command generates an .output directory that contains the app's contents ready to be served.

Hence, the baseDirectory property in Amplify's build config will need to be updated to .output/public. Hence, Nuxt's integration with AWS Amplify isn't zero config.

Happy to open a PR.

P.S: Nitro's docs might be misleading as well.

Open the affected Nuxt AWS Amplify documentation page and compare its zero-configuration guidance with the provided Amplify build configuration. Verify the required output directory and update the setup steps so they accurately describe deployment; done when the rendered page no longer claims zero configuration and reflects the working base directory.
