Unfortunately Gorn isn't a cross buy game (it's a developer decision), you'll need to buy it a second time to get it on PC.
If a game is cross buy, you need to go to the store page for the other platform (so if you bought the Quest version, go to the Rift store page for it) and the game will have a price of "Free". Select it as if you are buying it and you'll get the game on that platform added to your library.
