Update to remove GNOME 44 runtime dependency which is no longer supported

[butter-fly04]

Here is what Flatpak says:
Info: runtime org.gnome.Platform branch 44 is end-of-life, with reason: The GNOME 44 runtime is no longer supported as of March 20, 2024. Please ask your application developer to migrate to a supported platform.

This probably belongs to the flathub repository rather than the upstream app here, i.e. flathub/com.github.rajsolai.textsnatcher#3
Help is welcome!
