[FR] Alternative icons for Windows

[Wallby]

Description

For Android there are alternative icons since #5678

These are in https://github.com/AppFlowy-IO/AppFlowy/tree/main/frontend/appflowy_flutter/android/app/src/main/res

Could some alternative .ico files be included next to:
https://github.com/LucasXu0/AppFlowy/blob/2d26d8015ed233d3bd97fc64f68235dfec3e27ea/frontend/appflowy_flutter/windows/runner/resources/app_icon.ico

VSCodium has a repository for alternative icons on Windows: https://github.com/VSCodium/icons

Impact

You can't set png files as icons in Windows, so manual conversion is required to use one of the Android icons.
