GNOME Settings: Add VRR guide to "Display" docs
I will be helping with a university course where students will be contributing to our docs. I will be using the tw uni course label to tag those. These issues concern the recent design/UI changes in GNOME Settings in versions 45 and 46.
In https://help.gnome.org/users/gnome-help/stable/prefs-display.html.en we have some "how-tos" for "Display & Screen" related settings. This should include our newly added VRR (Variable Refresh Rate) settings in Settings -> Display.
This information will be in high demand by people wanting to optimize their gaming experience/performance in the GNOME desktop. For more info on VRR, check https://pcgamingwiki.com/wiki/Glossary:Variable_refresh_rate_(VRR)
The GNOME Settings changes are described here gnome-control-center!734 (merged) (with screenshots)
