signal-desktop: 5.27.1 -> 5.28.0

This update breaks Ozone/Wayland due to an Electron update [0].
This isn't ideal but we cannot block Signal-Desktop updates indefinitely
based on that. It's an upstream issue that is tracked by both
Signal-Desktop [1] and Electron [2]. Unfortunately, there are no known
fixes/workarounds yet.
