Add version to update window

[Bara]

Currently it just shows the changelog without any version number, which looks pretty weird.

This is what we got so far, but I'm pretty sure it'll stay like this - I've been trying to format the release body in a prettier way, but I'm extremely limited by the framework's controls and their capabilities. Also had a very hard time googling for better solutions with no luck.

It could also be because I'm dumb as a starfish, who knows.
