The vegalite_app artifact https://github.com/queryverse/VegaLiteBuilder/releases/download/v3.4.1/vegaliteassets-3.4.1-x86_64-w64-mingw32.tar.gz contains the following symlinks:

These are created when npm prune is called in the build script, though I'm not sure why.

This prevents Vega and VegaLite from being installed on Windows in Julia 1.10 due to stricter artifact integrity checking.
