Fix(notation): fixed legacy notation for Nix

[pimkoter]

There were still some old "Xorg.NAME was renamed to X" warnings in ./packaging/nix/package-desktop.nix

Thanks for tackling this, @pimkoter — clearing the xorg.* deprecation warnings is a welcome cleanup. A few things to sort out before it can go in:

1. Please drop / split the unrelated changes. Beyond the notation fix, this PR also does two things I'd like handled separately:

• release-data.json rewrites "hash" — the fetchFromGitHub source hash used by package-server.nix — for the already-released v2.14.0 (sha256-PdTD3o… → sha256-C+doF2…). That's unrelated to the desktop Xorg fix. If you hit a real source-hash mismatch it's worth its own PR with the nix-prefetch/nix build output so it can be verified; please revert it here.
• package-desktop.nix drops the nested WAYLAND_DISPLAY:+ guard on the ozone flag: NIXOS_OZONE_WL:+WAYLAND_DISPLAY:+--ozone-platform-hint=auto becomes NIXOS_OZONE_WL:+…, so the hint is now added whenever NIXOS_OZONE_WL is set even with no Wayland display. If that's intentional, please call it out and why; otherwise please keep the original guard.

2. Please keep the diff minimal. Most of the 142/133 is a whole-file reformat (indentation, list spacing). Trimming it back to just the ~12 buildInputs renames makes it easy to review and less likely to collide with the per-release edits to this file.

3. Verification. We can't build the Nix packages in CI or locally on our side (no Linux/Nix here), and the desktop derivation is x86_64-linux-only, so we can't confirm the flattened names (libx11, libxscrnsaver, libxtst, …) all resolve on the nixpkgs revision your users pin. Could you paste the output of a successful nix build .#zennotes-desktop plus the nixpkgs rev? That's the main thing standing between this and a merge.

Really appreciate the contribution — scoped down to just the notation rename plus a build log, this should be quick to land.
