weblate: remove package and module, only leave example (#333)

* flake.lock: Update

Flake lock file updates:

• Updated input 'nixpkgs':
    'github:NixOS/nixpkgs/154bcb95ad51bc257c2ce4043a725de6ca700ef6' (2024-08-09)
  → 'github:NixOS/nixpkgs/daf7bb95821b789db24fc1ac21f613db0c1bf2cb' (2024-08-14)

* weblate: remove package and module, only leave example

This is due to Weblate being merged into Nixpkgs:
NixOS/nixpkgs#325541

Poetry2nix was only used by Weblate, so I also removed that
