Fix update permission alert title text overlapping with question text (…

…#2284)

This change adjusts the layout constraints between the title and message text to be more proper.

This issue is only noticeable in Russian, Spanish, Ukrainian, and Slovenian on my machine.

Issue has been present in Sparkle 1 as well.
