Yeah, I meant devlogs. Based on your responses, I understand that this is simply a file version history, not the game files themselves. So, the old versions of the game no longer exist, and everything displayed on the screen is simply the game's version history, correct?

From what I understand, it's similar to GitHub. You have your game files in the final version, but you also have a change history, and it's supposed to be possible to recover an older version thanks to that history, but I've never tried it.
Butler manages that history automatically. Your players and the website should only see the latest version. If someone downloads your game, they only download the latest version and not the history, so it shouldn't be a problem.
