Update pacman to a patched version that does not deadlock on Windows/…

…ARM64

This downloads the PR build artifact of
msys2/MSYS2-packages#4583 and installs it in
`git-sdk-arm64`.

The idea is that the subsequent `sync` job runs as well as the
subsequent `build-and-deploy` runs in `git-for-windows-automation` won't
hang but instead succeed.
