### Bug description

With the new quarto 1.1.147 release we see the following error when rendering a book

(https://github.com/mlr-org/mlr3book/runs/8047883939?check_suite_focus=true#step:13:16)

```bash
In file book/_quarto.yml
(line 67, column 7 through line 68, column 23) Key code-tools has value toggle: true
      code-fold: false, which must be `true` or `false`
66:     code-tools:
67:       toggle: true
          ~~~~~~~~~~~~
68:       code-fold: false
    ~~~~~~~~~~~~~~~~~~~~~~
69:     highlight-style: printing
✖ The value toggle: true
      code-fold: false is object.
ℹ The error happened in location format:html:code-tools.
```


AFAICS our source specification https://github.com/mlr-org/mlr3book/blob/main/book/_quarto.yml#L66-L68 looks still valid when compared to the [quarto documentation source](https://quarto.org/docs/output-formats/html-code.html#code-tools) - is this a bug in the new release?
