feat: patch nextcloud-talk-desktop for Wayland screen sharing

Patches the Electron asar bundle to inject setDisplayMediaRequestHandler
with useSystemPicker: true, which routes screen capture through the
native PipeWire/xdg-desktop-portal pipeline on Wayland.

Based on upstream draft PR nextcloud/talk-desktop#1022.
Uses the patched version in communication role.
