Creatign the star

But it then asks you what test framework you want, with "None" being an option

If "None" is a valid option for test framework, the `Do you want to create a test project?` option is completely redundant. It could prompt immediately for `Select a test framework`, with `None` being an acceptable option

### Describe the solution you'd like

Remove the `Do you want to create a test project?` prompt, and always prompt for `Select a test framework`, perhaps with `None` being the first option.
