Correct omarchy-pkg-add AUR claim in AGENTS.md (#13895)

* Correct omarchy-pkg-add AUR claim in AGENTS.md

* Say omarchy-pkg-add installs from the pacman repos, not the official ones

It runs plain pacman -S, which also reaches the [omarchy] repo every shipped pacman.conf enables, so "official repos" would send an agent to the AUR helper for Omarchy's own packages.
