[bug] Nextjs route groups are not considered as a valid project

[RestartDK]

Describe the bug

When you import a nextjs project with route groups the validator fails to see if it's a valid nextjs project. For example:

src
└── app
    ├── (app)
    │   ├── about
    │   │   └── page.tsx
    │   ├── career
    │   │   ├── [id]
    │   │   │   └── page.tsx
    │   │   └── page.tsx
    │   ├── contact
    │   │   └── page.tsx
    │   ├── layout.tsx
    │   ├── news
    │   │   ├── [slug]
    │   │   │   └── page.tsx
    │   │   └── page.tsx
    │   ├── page.tsx
    │   ├── privacy
    │   │   └── page.tsx
    │   ├── projects
    │   │   └── page.tsx
    │   └── webcast
    │       └── page.tsx
    └── (dashboard)
        ├── admin
        │   └── page.tsx
        └── layout.tsx

Here it will not allow you to upload the nextjs project.

The expected behaviour should allow you to edit your projects regardless of route groups (as it technically only is a way to organise the app and does not implement any new functionalit).
