Desktop: Differential update does not work for windows

The updater expects the old blockmap to be present on the web server. At the moment, it will download the current blockmap twice since we don't change the file name between versions. The diff update then fails because the "old" blockmap doesn't match the old installer.

Any news on this ticket?

This was fixed with electron-builder 22.11.7, but the corresponding electron-updater version (v4.3.10) still hasn't been published to npm for some reason.
