niri module: noctalia now in Fedora repos, drop Terra dependency

noctalia 5.3.0 is in the Fedora 44 updates repo (confirmed on
packages.fedoraproject.org and by a fresh-install dnf install noctalia).
The niri module no longer calls add_terra_repo; Terra stays in the base
section and in the mango module, which is the only consumer left
(mangowc). README + comments updated.
