Fix launcher auto-updater

- Changed installation directory from /opt/appimages to
/opt/ankama-launcher
- Added post-install and post-upgrade instructions to add current user
to the "games" group in order to make the launcher auto-updater work
- Added post-remove instructions to help clean out all the leftover
files after removing the package

+The launcher has been removed, but the files and games it installed are still there. If you want to
+remove the launcher completely, have a look at the directories used
+by the launcher and remove them :
+- \$HOME/.config/Ankama/zaap
+- \$HOME/.config/zaap
+- \$HOME/.config/Dofus\\ Retro
+- \$HOME/.cache/zaap-updater
+Also, some games are using Wine, you might want to also take a look at your default Wine
+installation directory as there might also be leftover files there.
