[FFe] Replace cheese by gnome-snapshot in the desktop image

[Sebastien Bacher]

Replacing cheese by gnome-snapshot is on the desktop plans for this cycle but has been taking longer than expected (rust packaging complication + MIR delays). We got a +1 MIR review on the MIR bug #2052652 now and security team said they should have their review also done by the end of the week.

The rational for the change is that cheese has been in low maintenance mode for years and is quite buggy. GNOME switched their default camera application in GNOME 45 (a cycle ago).

It's also an oem team request since 22.04 to 'fix or replace" cheese since it has flaws which are problematic for hardware enablement. The fact that there was no action on fixing those problems since 22.04 is confirming that the project isn't really active anymore.

gnome-shapshot is also using the current gtk4 version (which will make it more consistent with the other desktop applications, cheese is still using gtk3) and libcamera which is making it compatible with newer mipi/ipu6 cameras.

The regression potential is limited since that's a standalone application mostly used to test the camera and do selfies and video recordings.

Hey Sebastien,

Thanks for filing this FFe. This looks OK, especially when it's a standalone application so it won't regress other parts of the desktop image. Consider this FFe approved.

Thanks, I've upated the desktop seed, now we will need an ubuntu-desktop refresh
