Update the docs on taking screenshots and screen recordings
GNOME has a new screenshot experience which will be landing in 42. It's fairly different from the old one, so it will be important to provide accurate documentation. The main page that will be affected is - https://gitlab.gnome.org/GNOME/gnome-user-docs/-/blob/master/gnome-help/C/screen-shot-record.page
Some aspects of the new experience are still in flux. By UI freeze things should have settled down, but it's worth making sure that everyone's in the loop in case something changes.
GNOME OS Nightlies provide a fairly easy way to test the new feature - just create a VM using the .iso, then update to the latest version by running sudo ostree admin upgrade
followed by a restart.
