### Bug description

I've moved to `quarto` from RMarkdown where it is possible to insert verbatim code chunks, as in this example document:

`````
---
title: "rmarkdown"
output: html_document
---

````{quarto}
---
output: html_document
---
  
```{r}
2+2
```

````
`````

However, in `quarto` this does not work:

`````
---
title: "{quarto}"
format: html
---

````{verbatim}
---
output: html_document
---
  
```{r}
2+2
```

````
`````

When using RStudio to render the `.qmd` document the following warning is generated:

```
In get_engine(options$engine) :
  Unknown language engine 'quarto' (must be registered via knit_engines$set()).
```

Which suggests if a code chunk is specified in an unknown language engine it defaults to the 'quarto' engine? Conversely, in RMarkdown if you provide an unknown language engine (eg `pretend`) there is an attempt to use that engine

```
Warning message:
In get_engine(options$engine) :
  Unknown language engine 'pretend' (must be registered via knit_engines$set()).
```
