How do I check if a game is availible on steam with an arduino uno?

I am new to this forum and somewhat new to programming. I am making a "Kerbal Space Program 2 celebration machine" that will activate a sequence of lights and sounds when Kerbal Space Program 2 is released. I know that I need to use an Ethernet shield to communicate to the internet, but how would I detect when the game is released and activate the lights and sounds?

You don't need an ethernet shield, they're expensive. More common these days is to use something like an ESP8266 or ESP32 or Wemos d1. Depending on your needs, you may be able to build the project with one of those alone, or you can use an Arduino with the other component handling wifi connectivity for you.

If you want to learn about internet connectivity and Arduino this is a nice project to get started. Without that requirement, I'd be more inclined to do the checking for game release on a PC and have it tell the Arduino when it sees it.

I have already purchased an Ethernet shield. Specifically, this one: Amazon.com I don't know if it is a good shield, but it was cheap (only about $10.) I want to know what code I would use to detect when the game is released, I think I would search the page Kerbal Space Program 2 on Steam for the text "Buy Kerbal Space Program 2" and if not found do nothing, if found, start the light and sound sequence. I just don't know what I would type into the arduino IDE to make the arduino do this.
