Error in download.file() in build_offline_repo.R

[parmsam-pfizer]

Lines 144 and 158 in build_offline_repo.R appear to use fs::path() to help build the download URLs, however on Windows the URLs are changed preventing download.

Here's what they look like:

> path(original_repo_location, "PACKAGES.rds")
https:/repo.r-wasm.org/bin/emscripten/contrib/4.3/PACKAGES.rds
> remote_package_info <- download.file(path(original_repo_location, "PACKAGES.rds"), destfile = path(full_package_path, "PACKAGES.rds"), mode = "wb")
Error in download.file(path(original_repo_location, "PACKAGES.rds"), destfile = path(full_package_path,  : 
  scheme not supported in URL 'https:/repo.r-wasm.org/bin/emscripten/contrib/4.3/PACKAGES.rds'

A simple solution would be to use file.path(original_repo_location, "PACKAGES.rds", fsep = "") for those lines.
