[NixOS] Prefer to enable packages via option when available

[Sigmanificient]

In NixOS, packages such as bat have associated options (programs.bat.enable = true) which should be preferred over the current proposition:

environment.systemPackages = with pkgs; [
    btop
];

List of packages with options

• OrcaSlicer via services.orca.enable
• Thunderbird via programs.thunderbird.enable
• brave via programs.chromium = { enable = true; package = pkgs.brave; };
• chrome via programs.chromium = { enable = true; package = pkgs.google-chrome; };
• chromium via programs.chromium.enable = true
• docker via virtualisation.docker.enable
• firefox via programs.firefox.enable = true
• firejail via programs.firejail.enable
• fish via programs.fish.enable
• foot via programs.foot.enable
• git via programs.git.enable
• kdeconnect via programs.kdeconnect.enable
• localsend via programs.localsend.enable
• nextcloud via services.nextcloud.enable
• openssh via services.openssh.enable
• podman via virtualisation.podman.enable
• qBittorent via services.qbittorrent.enable
• steam via programs.steam.package
• syncthing via services.syncthing.enable
• tailscale via services.tailscale.enable
• tor via services.tor.enable
• transmission via services.transmission.enable

• wireshark via programs.wireshark.enable

tried implementing this but the complexity/value ratio is way off. mapping every single pkg to a nixos module that might change is a maintenance nightmare. reverting to systemPackages to keep the repo sane. added to roadmap tho!

Steam should be at the very least using the programs.steam.enable module, otherwise users might encounter problems.
