Installs: Open button opens the Unity project, not the folder

The Projects list's Open action now launches the install's Unity project (the resolved Basis/Basis subfolder) in the editor matching its ProjectVersion, reusing the shell OpenProjectInUnityAsync path, which falls back to Unity Hub when that version isn't installed. Relabeled to Open in Unity and shown only when a Unity project is detected.
