Build Transmission Gtk4 Variant

[Sameer Sharma]

Currently the transmission Gtk client is Gtk3 variant only it would be good if we would use Gtk4 in respect to the modernity and version scheming
But this brings one major disadvantage- Lack of System Tray Icon as Gtk4 has no such mechanism.

This is currently not possible as both Jammy and the gnome-sdk doesnt offer gtkmm4 and related pkgs needed for building Transmission Gtk4.
Reported Upstream.

This is a nice article on building gtkmm4 atop Jammy. --> https://terminalroot.com/how-to-install-gtkmm-4-on-ubuntu-2204/

I guess we will have to do the labour by our-self of building gtkmm4 inside the snap itself. 🫠

This will need more time and resources as my initial attempts to manually build the needed deps has failed. Will re-look some other day or the snap devs should provide the latest gtkmm4 and needed libs in their sdk.

Using core24 is also an option but its restricted to dev releases.

Will Re-look with advent of Core24, Next Year.
