### Amplify Hosting feature

### Frontend framework

### Next.js version

### Next.js router

### Describe the bug

We're building and deploying a NextJS application on Amplify. We have a NX monorepo, and our NextJS app depends on local packages that we add thanks to pnpm workspaces.
However, as per our observation and the documentation, the linkage is done using symlinks which isn't correctly supported by Amplify.

https://docs.npmjs.com/cli/v7/using-npm/workspaces
https://pnpm.io/fr/cli/link

Example:
app is the NextJS application, it depends on the package 'some-dependency' locally
=> Runtime error thrown: Cannot find module 'some-dependency'

### Expected behavior

We expect pnpm workspaces to work with its symbolical linkage
Would you know of any alternative?

### Reproduction steps

1. Create a pnpm workspace dependency to your NextJS app
2. Run

### Build Settings

```yaml
version: "1.0"
applications:
- appRoot: apps/campus
frontend:
phases:
preBuild:
commands:
- echo "node-linker=hoisted" >> .npmrc
- echo "//npm.pkg.github.com/:_authToken=[GITHUB_TOKEN]" >> .npmrc
- corepack enable
- corepack prepare pnpm@8.3.1 --activate
- export NODE_OPTIONS=--max-old-space-size=8192
- pnpm install --shamefully-hoist --ignore-script
- cd ../..
- pnpm package
- cd apps/campus
build:
commands:
- env | grep -E '[SENSITIVE_VARIABLES]' >> .env.production
- pnpm build --no-lint
artifacts:
baseDirectory: .next
files:
- "**/*"
discard-paths: "yes"
exclude-paths:
- "**/cache/**/*"
```

### Additional information

_No response_

Start by reproducing the Amplify Hosting deployment described in the issue, using the provided applications build settings and pnpm workspace dependency. Investigate the reported Cannot find module error; done means the local workspace package resolves during the Next.js build and deployment.
