### Bug description

I'm having issues rendering the shinylive example document described [here](https://github.com/quarto-ext/shinylive). I followed the instructions for installing the extension which seemed successful. However, when I try to render the following example document:
```
---
title: Shinylive in Quarto example
format: html
filters:
  - shinylive
---

This is a Shinylive application embedded in a Quarto doc.

```{shinylive-python}
#| standalone: true

from shiny import *

app_ui = ui.page_fluid(
    ui.input_slider("n", "N", 0, 100, 40),
    ui.output_text_verbatim("txt"),
)

def server(input, output, session):
    @output
    @render.text
    def txt():
        return f"The value of n*2 is {input.n() * 2}"

app = App(app_ui, server)
```
it results in an error:
```
