create-next-app CLI needed --no-src-dir flag

[2chanhaeng]

Goals

1. Add --no-src-dir flag to create-next-app

Non-Goals

No response

Background

When creating a Next.js project with create-next-app, a flag is needed for cases where the src directory is not used. For now, it's impossible to create a project with a single-line command without additional input and without using the src directory.

Proposal

The create-next-app CLI needs a --no-src-dir flag or an equivalent for cases where the src directory is not used.
