Update folderify package version in Cargo.lock from 3.0.12 to 3.0.13

This updates the package version for folderify in Cargo.lock from 3.0.12 to 3.0.13 to match the latest release version.

context: I was trying to package this with Nix and the build was failing because the lock file is out-of-date

Thanks! I seem to have a race condition where this is not always committed consistently. 😭

Also, I don't know much about nix packages — let me know if there's something I should keep an eye out to avoid breaking in the future.

I'm not super familiar with them either, but I don't think there's anything specific to look out for except making sure that Cargo builds successfully with the --frozen option set.
