Feature Request: Add an option to uninstall/remove gaming packages

The welcome app features a one-click button to "Install Gaming packages", but there is no corresponding option to remove or uninstall them. If a user installs them and later decides they don't need the bundle, trying to clean it up via the "Remove orphans" button or pacman can aggressively target shared system dependencies, which risks breaking vital desktop environment components (like on Hyprland).

Describe the solution you'd like
Please add an official "Remove Gaming packages" button adjacent to the installation option that safely cleans out the gaming packages without breaking core system layouts or other installed user apps.

Start by locating the existing “Install Gaming packages” action in the welcome app and inspect how its package bundle is defined. Review the current “Remove orphans” and pacman behavior; done means an adjacent removal option removes the gaming packages without removing shared desktop dependencies or other user applications.
