Gnome Flatpak runtime no longer supported

[Scotty-Trees]

When running flatpak update I noticed a new warning as shown below:

Looking for updates…

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.
Info: applications using this runtime:
   com.github.GradienceTeam.Gradience, com.github.liferooter.textpieces, com.raggesilver.BlackBox, org.gnome.SoundRecorder, org.gnome.gitlab.somas.Apostrophe, org.gustavoperedo.FontDownloader

Please update the Gnome runtime to support the latest, thank you.
