anubis: repin the image ref to the lowercase ghcr path

podman's reference parser rejects mixed-case repository refs before any
network I/O ('repository name must be uppercase'); upstream's own install
docs pull lowercase (ghcr resolves case-insensitively). The first deploy
of this chain exit-2'd on that parse error — the image was not yet
pulled, so the guarded vhosts 502 until this deploy lands.
