build(app): the editor from its hosted fork

The app took the editor from our fork of AppFlowy Editor in a folder next to the
repository, which nobody else had, and which CI can't reach either. The fork now lives at
https://code.halkyon.app/project-halkyon/appflowy-editor (public; dual-licensed AGPL-3.0
or MPL-2.0 like upstream), on its branch halkyon/win32-v6, and the app depends on it by
git URL, pinned to the signed commit 0dac8a0. That commit adds `publish_to: none` to the
fork: it is a git dependency only, and the package name belongs to AppFlowy on pub.dev.
