pak::scan_deps() empty results when given file path(s) #844

Basic reprex is to create a folder with the following files:

test.R:

library(tidymodels)

test.qmd:

---
format: html
---

```{r}
library(tidyverse)

The following is the observed behavior when scanning from that directory:

pak::scan_deps()

Dependencies:

• rmarkdown @ test.qmd
• tidymodels @ test.R
• tidyverse @ test.qmd

pak::scan_deps("test.qmd", "./")

pak::scan_deps("test.R", "./")

pak::scan_deps(c("test.qmd","test.R"), "./")

In previous versions (not sure when this broke) of pak the latter three calls would have returned the file specific dependencies.
