### Bug description

Using `lang: pl` causes Quarto to show this error:

```
[WARNING] Could not load translations for pl
  translations/pl.yaml: YAML parse exception at line 3, column 9:
  mapping values are not allowed in this context
[WARNING] The term Abstract has no translation defined.
```

Other languages work. `_language_pl.yml` seems fine.

`quarto check` output:
