v4.6.0

• Since this release Linux users get back the GTK / Appindicator-based tray icon implementation. The one that was used before v4.3.0 rolled out. So the D-Bus-based tray icon adopted by @electron from the upstream @chromium project is no longer used which allowed reverting the #254 related code changes in the app code base. See #254 and @electron's #23674 for details.
• Enable virtual Unread folder in local store view mode (#249, a4f7580).
• Enable up / down keyboard navigation in local store view mode (#234, ff84d38).
• Improve folders drop-downs appearance consistency in local store view mode (#249, 0c5a6d3).
