Describe the Bug

With the release of v13 every time a command / script is run, whether that be dev, build, etc, Next.js will always generate a new .gitignore & .vscode/settings.json file.

Not breaking in anyway but really not needed. Especially when using a monorepo, like Turborepo & I already have these files top level so Next.js is just generating extra files that are not needed.

Expected Behavior

Either not generate them at all (Though I know there is of course a reason to actually provide these files / config to users) or not generate them if it is (somehow) detected to be running inside a monorepo.

To Reproduce

Create a new Next.js project & run either next dev or next build & it will generate a new .gitignore if one does not already exist or append .vscode to your existing .gitignore & similarly either create or append to .vscode/settings.json
