Citation of R packages directly on Quarto

[jospueyo]

Description

How nice it would be having a function to directly cite R packages in Quarto? Something like:

r citation(<package>) and the output becoming a reference as any other reference.

I tried doing a custom function with the following workflow:

1. Extract the information using citation()
2. Use rmarkdown::metadata$bibliography to obtain the bibliography file.
3. Use writeLines() to add the reference to the bib file.
4. Output a markdown reference @.

However, the problem is that the changes in bibliography are persistent so it does not work when render the file a second time. I would be keen to do a pull request if I receive some guidance on how to surpass this problem.
