### Bug description

Putting `references.bib` (or a csl file, as I was attempting) in a subdirectory Quarto does not find it for HTML only.

For a reprex, create a Quarto book from template (say, `quarto create-project mybook --type book`)
Then place the .bib fiile in a new directory called `subdir` then modify `_quarto.yml`, line 15.

That should create the following key files:

#### index.qmd

```
# Preface {.unnumbered}

See @knuth84 for additional discussion of literate programming.
```

#### references.qmd

```
# References {.unnumbered}

::: {#refs}
:::
```

#### _quarto.yml

```
project:
  type: book

book:
  title: "issue3949"
  author: "Jane Doe"
  date: "12/01/2023"
  chapters:
    - index.qmd
    - references.qmd

bibliography: subdir/references.bib

format:
  html:
    theme: cosmo
  pdf:
    documentclass: scrreprt
````

#### subdir/references.bib

```
@article{knuth84,
  author = {Knuth, Donald E.},
  title = {Literate Programming},
  year = {1984},
  issue_date = {May 1984},
  publisher = {Oxford University Press, Inc.},
  address = {USA},
  volume = {27},
  number = {2},
  issn = {0010-4620},
  url = {https://doi.org/10.1093/comjnl/27.2.97},
  doi = {10.1093/comjnl/27.2.97},
  journal = {Comput. J.},
  month = may,
  pages = {97–111},
  numpages = {15}
}
```

If I render to PDF this works fine, Rendering to HTML leads to 

> File subdir.bib not found in resource path
> ERROR: File subdir.bib not found in resource path

Dashes seem to preserve some of the name as `bibliography: subdir/references-2.bib` leads to 

> File subdir-2.bib not found in resource path

This is on Quarto version 1.2.313,
