wolf: add optional ES-DE/RetroArch AppImage downloads for Steam Input
Both projects ship official standalone Linux AppImages separate from the esde/retroarch Wolf catalog containers this repo already runs. Adding either one to Steam as a non-Steam game (steam-add-nonsteam-game, now reaching the same roms/saves/bios/retro-home/retroarch mounts as the esde/retroarch containers) lets Steam Input assign a 4th controller its own identity by device path, past Wolf's 3-concrete-pad-type ceiling. ES-DE is hosted on GitLab rather than GitHub, so this adds a GitLab Releases API counterpart to the existing GitHub-based download helper. RetroArch's own buildbot doesn't publish through either API, so this uses hizzlekizzle/RetroArch-AppImage, the community nightly-build project the AppImage catalogs themselves point to (flagged as third-party, same treatment this file already gives the Dolphin community build). Both downloads are opt-in (default no) and symlink to a fixed filename so steam-add-nonsteam-game's case-sensitive substring match finds them regardless of the vendor's own asset name.
