Cannot import simple exported collection

### Expected Behavior

I can import a simple exported collection into version 2023.2.2.

### Actual Behavior

The import fails and just shows the message "The provided document does not match any of the registered formats."

### Reproduction Steps

1. Create a new collection.
2. Create a new simple request.
3. Click on collection name at the top.
4. Click on "Import/Export".
5. Click on "Export data".
6. Choose to export only the collection.
7. Export everything as Insomnia V4.
8. Goto projects.
9. Click "Create" -> "Import" and choose file.
10. Select file to import.
11. After import, the collection is empty with the warning message shown in "Actual behavior".

### Is there an existing issue for this?

- [X] I have searched the [issue tracker](https://www.github.com/Kong/insomnia/issues) for this problem.

### Additional Information

It seems like Insomnia tries to import the collection as a document, because after importing a new document (instead of collection) is added to the project.

Import works fine with version 2023.1.0.

Reproduce the Import/Export flow using the listed steps on Windows, comparing Insomnia 2023.2.2 with the last known working 2023.1.0. Trace why an exported Insomnia V4 collection is imported as a document and ends up empty; done means the collection imports with its request and without the registered-format warning.
