Update TablePlus to GTK 4 and Adwaita theme

[gxanshu]

I love TablePlus, thank you for creating such an excellent product.

GNOME has evolved significantly, and the latest version follows a design language based on GTK 4 and the Adwaita theme, which feels much more native to the platform.

I believe TablePlus currently uses GTK 3 components. Updating to GTK 4 and adopting the Adwaita theme would make TablePlus look and feel more polished and seamless on Linux.

Thank you again for this wonderful tool.
