Update Adwaita and Adwaita-dark themes
the Adwaita and Adwaita-dark themes shipped in gtk-common-themes are greatly outdated and create a mismatch between snaps and other apps (debs/flatpaks/appimages) when using Awaita on the system and even breaks some UI elements on some apps.
Please update Adwaita and Adwaita-dark shipped in gtk-common-themes to their latest versions.
