v0.1.7 — fix AMD Steam bootstrap, drop redundant deps

Steam was failing to bootstrap on AMD systems during install. The homegrown
`setsid gtk-launch steam` path silently no-op'd when `gtk-launch` wasn't
available (gtk3 isn't a hard dep of `steam` or any AMD-specific package, so
leaner AMD setups never had it; NVIDIA systems usually pulled it in via
nvidia-settings).

Now delegates to `omarchy-install-gaming-steam`, which is the canonical
install + bootstrap path on Omarchy and is exercised on AMD/Intel/NVIDIA
by the upstream Omarchy tests. It's idempotent — `omarchy-pkg-add steam`
no-ops if Steam is already present.

Cleanup pass on dep lists now that the bootstrap is delegated:

- core_deps: drop `steam` (installed by omarchy-install-gaming-steam) and
  `mesa-utils` (glxinfo/glxgears never called by the script).
- gpu_deps: drop `lib32-nvidia-utils`, `lib32-nvidia-580xx-utils`,
  `lib32-vulkan-radeon`, `lib32-vulkan-intel` — all now installed by
  `omarchy-install-gaming-gpu-lib32` (called by omarchy-install-gaming-steam).
- optional_deps: drop `xf86-video-amdgpu` — X11 DDX driver, useless under
  Hyprland (Wayland-only).
- setup_requirements: drop `steam` from required_packages (same reason
  as core_deps).

64-bit GPU drivers (`vulkan-radeon`, `vulkan-intel`, `nvidia-utils`, etc.)
kept because `omarchy-install-gaming-gpu-lib32` only handles the lib32 side.
