[Bug] AppImage fails to start on Fedora 44: libmount.so.1: version 'MOUNT_2_40' not found

### Bug Description

The AppImage bundles an outdated libmount.so.1 in usr/lib/x86_64-linux-gnu/. On systems with a newer system libglib-2.0.so.0 (which requires MOUNT_2_40), this causes the bundled libmount.so.1 to be loaded instead of the system one (due to LD_LIBRARY_PATH prioritizing the AppImage's bundled libs), and the app fails to start.

### How to Reproduce

Download the latest AppFlowy AppImage
2. chmod +x AppFlowy*.AppImage
3. Run ./AppFlowy*.AppImage from a terminal
4. See error
5. Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
/tmp/.mount_AppFlozd5Wdx/AppFlowy: /tmp/.mount_AppFlozd5Wdx/usr/lib/x86_64-linux-gnu/libmount.so.1: version `MOUNT_2_40' not found (required by /lib64/libgio-2.0.so.0)
/tmp/.mount_AppFlozd5Wdx/AppFlowy: /tmp/.mount_AppFlozd5Wdx/usr/lib/x86_64-linux-gnu/libpcre2-8.so.0: no version information available (required by /lib64/libglib-2.0.so.0)

### Expected Behavior

The AppImage should start normally, using the system's libmount/libpcre2 where they're newer, or bundle a version compatible with current glib releases.

### Operating System
