PS4 workflow: Use pacman-package-manager

Switches from `pacbrew-pacman` to vanilla pacman that is now an Ubuntu package (`pacman-package-manager`) starting from Ubuntu 24.04.

pacbrew-pacman from https://github.com/PacBrew/pacbrew-pacman/releases is 2 years old and has the repo URL that no longer works.
With the vanilla pacman, we simply add pacbrew as a repo source with the correct URL.
