No bs4_book chunk line numbering

[moondog1969]

I am unable to obtain chunk line numbers in bs4_book. When using:

# Test 1

```{r, attr.source='.numberLines'}
1 + 1
```

I get:

Note the lack of line numbers in the chunk input. My YAML header is:

---
title: "Test"
author: "Author"
date: "2025-01-22"
output:
  bookdown::bs4_book:
---

bs4_book() is leveraging R package downlit to highlight R chunk as mentioned in the documentation
https://bookdown.org/yihui/bookdown/html.html#bs4-book

and there is an issue with numberline support

• downlit_html_* should support Pandoc's document with numbered line r-lib/downlit#133

So this needs to be fixed upstream so that it can work in bookdown
