Describe the Bug

I am trying to create a top-level root page dynamically according to the docs (https://docs.astro.build/en/core-concepts/routing/#example-dynamically-create-a-top-level-root-page) it works fine for the default build format directory, but when switching to build format 'file', the index.html is generated into the top-level project-directory instead of dist.

If someone points me to the place, where the file path is derived from the URL, then I could submit a pull request for this.
