Template not working out of the box

Hi guys,
can someone provide

## Issue 1: working a package.json and amplify.yml

that's working with next js 15, node 21.5 ? I have too many unresolved dependencies and the pipeline never works.
Thanks

## Issue 2: do we have to put all files into root or can we build it within a folder structure like this:
- project_name/amplify
- project_name/src/app
- project_name/root files
- amplify.yml

### Some more infos:

### Environment
- Node.js Version: v21.5.0
- npm Version: 10.2.4

### Issues
- Several packages are reporting that the current Node.js version (v21.5.0) does not meet their required engine specifications (20 || >=22).

### Graph

```
[AmplifyDataConstructInitializationError] Failed to instantiate data construct

Ensure that there is only one instance of "graphql" in the node_modules
directory. If different versions of "graphql" are the dependencies of other
relied on modules, use "resolutions" to ensure only one version is installed.

https://yarnpkg.com/en/docs/selective-version-resolutions

Duplicate "graphql" modules cannot be used at the same time since different
versions may have different capabilities and behavior. The data from one
version used in the function from another could produce confusing and
spurious results.
```

Start by inspecting the repository's package.json and amplify.yml, then reproduce the reported install and pipeline failures with the listed Node.js version. Check the documented project layout and the AmplifyDataConstructInitializationError involving duplicate graphql modules. Done means a supported configuration and folder structure are documented or validated without the reported dependency and pipeline failures.
