bug: Missing Linux launch related Spanish localizations

[0neGal]

It seems I managed to miss this when merging #229, but the Spanish localizations only has 2 of the titles for the new toasts instead of all of them + the text... This is where I recommend using npm run langs:localize over manually editing :p

Though, I suppose this is my fault for never getting around to making some CI/CD for checking localizations... This is now added with 5ddec75

Specifically these are missing (@XNovaDelta):

es.json is missing:
  gui.toast.title.missing_steam
  gui.toast.title.missing_flatpak
  gui.toast.title.missing_flatpak_steam
  gui.toast.desc.failed_launch_command
  gui.toast.desc.missing_launch_command
  gui.toast.desc.missing_steam
  gui.toast.desc.missing_flatpak
  gui.toast.desc.missing_flatpak_steam

Well, I got curious, and discovered I accidentally broke the checking of the localization files when publishing a build (ccde19d8), the entire reason why I never noticed this when releasing, that issue is fixed now: 877d0e5
