feat(infobox_extensions): create automated game appearances for playe…

…rs (#4178)

* feat: add GameAppearances as Extension module

* 1st attempt at fixing

this is gonna take a while to figured it out

* 2nd attempt

* 3rd

* return string

* Update infobox_extension_game_appearances.lua

* Update infobox_extension_game_appearances.lua

* With the suggested changes

I still need a way for this extension to catch Underscores vs non-Underscores cases. That would be the last thing needed before this can go merged

* Update infobox_extension_game_appearances.lua

components/infobox/extensions/commons/infobox_extension_game_appearances.lua
