### Bug description

According to <https://quarto.org/docs/authoring/title-blocks.html#metadata-labels>, `affiliation-title` can be used to change the block title, but it does not work.

```qmd
---
title: "Untitled"
lang: fr
author:
  - name: "Mickaël"
    affiliation: "Institut Pasteur de Lille"
affiliation-title: "Affiliation"
author-title: "Test"
format: html
---
```

while using `language` we can override the block title.

```qmd
---
title: "Untitled"
lang: fr
author:
  - name: "Mickaël"
    affiliation: "Institut Pasteur de Lille"
author-title: "Test"
language: 
  title-block-affiliation-single: "Affiliation"
  title-block-affiliation-plural: "Affiliations"
format: html
---
```

OS: MacOS (arm64)
