### Describe the bug

When I try `sanic module:app` it works.
When I try `sanic -d module:app` it doesn't.  Trying --dev doesn't work.  I can run with `-r and --debug` separately.

```
$ sanic testapp:app --dev

Discussion:
Any more specifics about the OS? I ran into something similar today when running in docker and I assumed it was because of something with stdin.

In short, you can solve by adding `--no-repl` for right now. 
Just WSL2, Ubuntu 23.10, Windows 11
`variable_descriptions` is a static list of length 3. There is no `[3]` index to do `del variable_descriptions[3]`.

```py
        variable_descriptions = [
            f"  - {Colors.BOLD + Colors.SANIC}app{Colors.END}: The Sanic application instance - {Colors.BOLD + Colors.BLUE}{str(app)}{Colors.END}",  # noqa: E501
            f"  - {Colors.BOLD + Colors.SANIC}sanic{Colors.END}: The Sanic module - {Colors.BOLD + Colors.BLUE}import sanic{Colors.END}",  # noqa: E501
            f"  - {Colors.BOLD + Colors.SANIC}do{Colors.END}: An async function to fake a request to the application - {Colors.BOLD + Colors.BLUE}Result(request, response){Colors.END}",  # noqa: E501
        ]
```
there is a quick 'solution' without any changes of the current code: `pip3 install httpx`  :)
