Hello, I was trying `quarto` on the following example:

````
---                         
title: document_01          
author: statquant           
toc: true                   
toc-depth: 2                
format:                     
  html:                     
    max-width: 800px        
    fontsize: 18px          
    html-math-method: katex 
jupyter: ir                 
---                         
                            
That's a test               
                            
```{r}                      
#| echo: false              
plot(1:5)                   
```
````    

and running `quarto convert document_01.qmd` `document_01.ipynb` got generated but opened in `jupyterlab` as follows:

Is there additional yaml I should be adding ?

PS: 
- Sorry for the missing ticks in `document_01.qmd` I could not have them displayed properly
- The document mentions `quarto convert document.qmd --to xxx` while on the version I got it should say `quarto convert document.qmd --output xxx` (I think as the first errors while the second passes). Happy to PR this documentation change if that's any useful
