Use lootGameName() and displayGameName() in initial places

# Motivations
- ModOrganizer2/modorganizer-game_ttw#36 (comment) Surfaced desires to change the Fallout TTW plugin's gameName to something more obvious, from TTW to Tale of Two Wastelands, but that would cause existing profiles to break, `displayGameName()` added in ModOrganizer2/modorganizer-uibase#141 gives us the option to change the way the game plugin is displayed, but leaves the existing integral `gameName()` alone
- Similarly ModOrganizer2/modorganizer-game_ttw#36 attempted to fix the sort button LOOT cli argument by changing the `gameShortName()`, as 'TTW' isn't a valid option for LOOT, but that comes with some pretty concerning possible issues

# Modifications
- Use `displayGameName()` in create instance dialogs & the main window, this doesn't cover all places `gameName()` was being used for purely display reasons, but it covers the bulk
- Use `lootGameName()` instead of `gameShortName()` for LOOT cli initiation
