Layout can't be located in folder with routing v2

[ziimakc]

What version of Remix are you using?

1.11.1

Are all your remix dependencies & dev-dependencies using the same version?

• Yes

Steps to Reproduce

npx create-remix@latest

Switch to V2 routing, and run remix routes

Expected Behavior

Following layout should work no matter if files or the same folders with index.tsx inside are used:

user.$id/index.tsx - user layout
user.$id._index/index.tsx - nested in user layout

    <Route path="user/:id" file="routes/user.$id.tsx">
      <Route index file="routes/user.$id._index.tsx" />>
    </Route>

Actual Behavior

Works:

user.$id.tsx - user layout
user.$id._index.tsx - nested in user layout

    <Route path="user/:id" file="routes/user.$id.tsx">
      <Route index file="routes/user.$id._index.tsx" />>
    </Route>

Doesn't:

user.$id/index.tsx - user layout
user.$id._index/index.tsx - nested in user layout

Error: Path "/user/:id" defined by route "user.$id._index/index" conflicts with route "user.$id/index"

After some testing I can say that user.$id._index/index.tsx can be located in folder, but not it's layout user.$id/index.tsx that needs to be a file user.$id.tsx
