Update DiscordStatus to v1.4.0

[andrewburgess]

DiscordStatus

• Adds ability to pull "detectable" game list from Discord so that those client IDs can be used when reporting current app
  • Previously, the plugin would use it's own AppId, which resulted in a Discord status saying "Playing SteamDeck"
  • Now, if a game can be matched against Discord's "detectable" list, then that AppId will be used, resulting in the correct game name being displayed in the rich presence
