[Feature request] Synchronise window border color with GNOME accent color

[vinchatl]

GNOME 47 introduced 9 accent-colors to choose from in the Settings:

It would be nice to be able to synchronise the window border color with GNOME's accent color automatically. I'm currently doing it manually, it is not difficult to do, but it would be amazing to have it done directly by your extension!
This page may help for background implementation since you're using libadwaita. It would probably also require to add a toggle button in the Preferences page in the Window border section.

If you want to go even further, there are also extensions to customise the desktop accent color like Custom Accent Colors or even to synchronise it with the wallpaper dominant color like Auto accent colour. I don't know they work and if that means a lot of work to support their implementation.
