allow BioConductor packages to be detected

[zkamvar]

This provides a second chance to install bioconductor packages that were missed on the first pass by implementing the strategy in #365 (comment), which is to prepend the package name with bioc:: and re-run renv::install().

Here's an example using the a4Core package (literally the first small package I could find in BioConductor)

> writeLines("library(a4Core)", "episodes/test.R")                                                                                                                            

> sandpaper::manage_deps()

The following package(s) will be updated in the lockfile:

# Bioconductor =======================

* Lockfile written to '/tmp/Rtmp1qs2zv/file2e86154489848/renv/profiles/lesson-requirements/renv.lock'.

I've also tested this locally on other repositories, but I will wait until I do the integration test to release.

This will address #365
