Add a way to view change logs from app

[kisunji]

Unsure if the button is a placeholder since I don't see it on nightly but it would be nice to see what updates are being made to the nightly tags!

The change log button is a placeholder in v1.2.1, I have considered making it functional in the future, but it is currently low priority. It is also removed in place of a "force update" button in the current nightly release.

Unfortunately, the only way to follow changes right now is to follow the commit history. I will have to look into displaying those changes properly on the nightly release draft page (they are currently not being updated to display recent commits made, tracking #101).

@lulzsun I believe this would be an good area to focus on to improve the application's user-friendliness. Do you have any idea on the best way to implement it?
