net-im/telegram-desktop: Bump to 4.0.2

Turns out they never really dropped Qt5 support, only for some wayland
integrations. I've tried to research what this means but I actually have
no idea beyond some mentions of "xdg-shell".

This is why I warn about it in the postinst, even if it may not be
meaningful...

Debian ships the package the same way.
