bslib dependencies fail during file copy when installed read-only #1154
Description
Permission denied when using precompiled css from a read-only bslib installation
In enterprise settings it is not uncommon to have a centralized library of packages where everything is installed read-only and maintained by designated users/teams. Another use case which is quickly gaining popularity is using Nix package manager for maintaining data science environments. Nix also installs everything read-only.

One solution would be to add copy.mode = FALSE to the file.copy calls, so that the file mode attributes are not preserved.
This fails in applications that call bslib internally, like elmer
