wolf: fix stale command list in the post-install summary, surface the Steam Input workflow

The final echo summary still advertised a removed `apps` command and left out
everything added since (cores, backup, controllers, steam-add-nonsteam-game,
steam-setup-frontends, cemu-clone-controller, cemu-sync-controllers,
install-completion, etc.). Also add a short pointer to the Steam-as-4-controller-hub
workflow (documented in depth further down in README.md) right in the install
summary, since it's currently only discoverable by reading the generated README.
