Description of the problem

Extra files are shown in the explorer. See GitHub: https://github.com/algolia/create-instantsearch-app/tree/templates/autocomplete

vs codesandbox:

That folder actually exists, but is a sibling to the /autocomplete folder, not inside of it

How has this issue affected you? What are you trying to accomplish?

confusing files show up, and cause people to edit things that aren't displayed

To Reproduce

open the sandbox: https://codesandbox.io/s/github/algolia/create-instantsearch-app/tree/templates/autocomplete
see that the files aren't the same as on GitHub: https://github.com/algolia/create-instantsearch-app/tree/templates/autocomplete

Link to sandbox: link

Your Environment

Start with the CodeSandbox GitHub project import for the templates/autocomplete tree and compare its fetched files with the linked GitHub directory. Reproduce using the provided CodeSandbox link; done when the explorer matches the GitHub tree and does not show the sibling folder's files inside autocomplete.
