bundle install doesn't install pacman dependencies

[larskanis]

What problems are you experiencing?

bundle install doesn't install pacman dependencies.
psych has the msys2_mingw_dependencies set here.
Automatic installation of libyaml works with bundler up to 2.4.22, but fails with bundler-2.5.x.

Steps to reproduce

Use a Gemfile like this:

source 'https://rubygems.org'
gem "psych"

Ensure pysch and libyaml are unavailable:

$ ridk exec pacman -R mingw-w64-ucrt-x86_64-libyaml
$ gem uninst psych

Run bundler to download and install psych:

$ bundle
