`renv::update()` with pak errors when `packages =NULL`

[Aariq]

Without pak enabled, renv::update() with no arguments updates all packages in the lockfile. With pak enabled, it errors as follows:

> renv::update()
Error: 
! error in pak subprocess
Caused by error in `find_package_root(path = root)`:
! Could not find R package in `/Users/ericscott/Documents/GitHub/usa-npn/thermal-trends` or its parent directories.

4: pak$local_install_dev_deps(root = project, lib = lib, ask = prompt)
3: remote(function(...) {
       get("local_install_dev_deps_make_plan", asNamespace("pak"))(...)
   }, list(root = root, lib = lib, upgrade = upgrade, start = start, 
       dependencies = dependencies, loaded = loaded_packages(lib)))

Thanks; I've made some changes on main to support this workflow with pak. Any chance you would be able to test and report back if it works as you expect?

[Aariq]

Yup, works as expected now!

Great, thanks for confirming!
