Multiple bookdown document types causes renv to remove bookdown

[grasshoppermouse]

Fresh renv project with a new Rmd file. bookdown is installed and correctly entered in the renv.lock file.

This YAML does not result in any unexpected behavior from renv::status():

---
title: "Test"
author: "Test"
date: "3/9/2021"
output: 
  bookdown::pdf_document2:
   number_sections: false
---

> renv::status()
* The project is already synchronized with the lockfile.

This YAML, on the other hand:

---
title: "Test"
author: "Test"
date: "3/9/2021"
output: 
  bookdown::pdf_document2:
   number_sections: false
  bookdown::html_document2:
   number_sections: false
---

results in this output from renv::status()

> renv::status()
The following package(s) are no longer used in this project:
           _
  bookdown   [0.21]

Use `renv::snapshot()` to remove them from the lockfile.
