[Page layout](https://quarto.org/docs/output-formats/page-layout.html) gives a code example that produces an error of "ERROR: Render failed due to invalid YAML."

The example shows as:
```
format: 
  html:
    page-layout: full
```

I believe the example should be shown as:
```
format:  html
page-layout: full
```
