[🐛Bug]: libayatana-appindicator deprecation warning appears on Linux startup

[Linming-XHL]

✨ What You Expected

When launching BongoCat on Linux, I expect the application to start without deprecation warnings, or to use the maintained libayatana-appindicator-glib backend for the system tray icon.

❓ What Actually Happened

When launching BongoCat from a terminal, the following warning is printed:

(bongocat:5188): libayatana-appindicator-WARNING **: 08:20:13.155: libayatana-appindicator is deprecated. Please use libayatana-appindicator-glib in newly written code.

BongoCat still runs and the tray icon appears to work, but the warning is noisy and indicates the app is linked against a deprecated library. This may become a compatibility issue in the future if libayatana-appindicator is removed or no longer packaged by distributions.

📝 Steps to Reproduce the Issue

1. Use the latest version of BongoCat on Linux.
2. Launch BongoCat from a terminal.
3. Observe the terminal output during startup.
4. The libayatana-appindicator is deprecated warning appears immediately.

📌 Platform

Linux - KDE Plasma
