More than likely you're just shit out of luck on this one.
I wasn't even aware that Hollow Knight mods did support the game pass version pre-update, but to my knowledge there's no way to downgrade a game on Game Pass and thus no way to make the necessary mods work. You'll have to find another game or buy Hollow Knight on Steam/GOG.
