Fix Windows export: include examples/shared/ dependencies

The export_presets.cfg excluded examples/shared/** from both Windows
Desktop and Linux Server presets. The multiplayer-fps.tscn main scene
depends on files in this directory (network-popup.tscn, async.gd,
simple-time-display.gd) — without them the exported binary crashes
on startup with 'Can't load dependency' errors.

- Remove examples/shared/** from Windows Desktop exclude_filter
- Remove examples/shared/** from Linux Server exclude_filter
