[`rTexPacker`] Unable to save project on Fedora Linux

[jhayden02]

Version: rTexPacker v5.5 Linux (x64)
System: Fedora Linux 43
Kernel: 6.17.12-300
DSP: Wayland

When attempting to save a project to an *.rtp file, I get no dialog box.

I attempted the same thing while loaded into an X11 session of Fedora 43 (to see if it's Wayland-related) and got the same results: no dialog box.

@jhayden02 thanks for reporting, I'll review it as soon as possible
