Okay. It's a bit tricky to get there, but the code and data are uncompressed. They're also too big and weird to be useful, probably.
But that's a silly way to look at it. My games are open source. By all mean, take the code and reuse it. Does it even work in GDevelop? Are you even making the same kind of game?
Most likely people don't need your code. Just worry about making games.
