The deb's /etc/cron.daily/microsoft-edge runs a script that writes an apt keyring to /usr/share/keyrings every day. pacman doesn't track that file, so it stays behind after Edge is removed. Remove the cron job and its script the way the Chrome recipe already does, and skip the empty /etc left behind. pkgrel 2 so this build replaces AUR-installed copies. Found in a Codex review.
