* Linux: Export symbolic icon in Flatpak manifest
* GitHub Actions: Add Flatpak action
Help make sure any Linux changes don't break the Flatpak build.
* GitHub Actions: Add Godot PCK export
Helpful for testing Linux releases
* MetaInfo: Update release info
* Linux: update metainfo for 2025.01.16 release
I also corrected the last screenshot caption; I said 18 levels for some reason when it's five worlds and over 30 levels.
* Linux: Update Flatpak manifest with latest PCK release
